    Hey,

    We're seeing this crash below semi frequently in our game built with Unity 5.1.1p1, IL2CPP, and universal ARM v7/64-bit.

    I think this is a bug that happens some times when using the WWW class. We're using it quite frequently in our game.

    Seems to happen at random locations when fetching JSON text data from the web.

    Is anybody else seeing the same crash?

    I've just hit this as well, not super sure what's up with this. Unity 5.1.1p3

    I'm seeing an identical crash on IL2CPP and Mono2x.

    This is not an issue in 5.0.3p2.

    Woopie! I've resolved the error by adding a "yield return new WaitForEndOfFrame();" at the beginning of my coroutine before my WWW declaration.

    Code (CSharp):
    1.  
    2.        private IEnumerator LoadMaterialTextureCoroutine(string path, Material material)
    3.         {
    4.             yield return new WaitForEndOfFrame();
    5.  
    6.             WWW textureLoad = new WWW("file://"+path);
    7.  
    8.             // This is done in favor of yielding on the WWW variable due to Unity throwing a harmless "Coroutine continue failure" error in editor.
    9.             // Bad -> // yield return textureLoad;
    10.             do
    11.             {
    12.                 if ((null == textureLoad) || !string.IsNullOrEmpty(textureLoad.error))
    13.                 {
    14.                     Debug.LogErrorFormat(this, "Texture Loading Failed!\nPath: {0}\nError: {1}", path, textureLoad.error);
    15.  
    16.                     yield break;
    17.                 }
    18.  
    19.                 yield return new WaitForEndOfFrame();
    20.             }
    21.             while (!textureLoad.isDone);
    22.  
    23.             if ((null != material) && material && material.HasProperty("_MainTex"))
    24.             {
    25.                material.mainTexture = textureLoad.textureNonReadable;
    26.             }
    27.  
    28.             this.renderer.materials = new Material[]{material};
    29.  
    30.             yield break;
    31.         }
    32.  
    It appears calling multiple coroutines with WWW initializations at the beginning triggers this issue; my best guess is that by adding a frame delay it allows Unity to stagger them.

    Again, this only showed up in 5.1.1, I was definitely not seeing it in my previous version of 5.0.3p2.

    I ran into this crash after updating unity yesterday as well!! This is a pretty severe issue because I am unable to figure out what is causing this crash since everything was working fine before the update. Considering that some of the plugins I am using are DLL's without the source, if the crash is happening inside that, I can't even fix it! Can Unity please take a look at this

    - (void)connection:(NSURLConnection*)connection didReceiveData:(NSData*)data

    {

    if(self->_data == nil)

    {

    size_t capacity = self->_estimatedLength > 0 ? self->_estimatedLength : 1024;

    self->_data = [NSMutableDatadataWithCapacity: capacity];

    }


    [self->_dataappendData:data];

    UnityReportWWWReceivedData(self.udata, [self->_datalength], self->_estimatedLength); ---- EXC_BAD_ACCESS


    if(self.shouldAbort)

    [connection cancel];

    }

    domination`UnityReportWWWReceivedData:

    same crash here with 5.0.2p4. But for me it's somewhere in the parse.com dll so there's not much that I can do about it.

    Hi,
    same crash for me as well with Unity 5.1.2. It's happening when closing the "purchase complete"-popup after IAP. It was working with an older version of Unity, though.
    Did anyone find a fix for that UnityReportWWWReceivedData crash? Can't submit the game to Apple like this...
    Thank you!

    I also got this error on iOS and found that UnityReportWWWReceivedData() crashed when a UnityEngine.WWW instance had already been Dispos()ed. WWWConnection.mm has the following difference between 5.0.x and 5.1.x, which seems to cause this very timing-related issue.

    Hey, thanks for posting this! But how do you apply this patch? I tried using patch from command line I got the error :
    patch: **** malformed patch at line 11: }

    The above code shows only the diff of 5.1.0 since 5.0.2p4 and cannot be applied as a patch to fix the issue. Please edit the file manually and replace the following,
    Code (CSharp):
    1.     dispatch_async(dispatch_get_main_queue(), ^{
    2.         delegate.connection = [NSURLConnection connectionWithRequest:request delegate:delegate];
    3.     });
    4.  
    with the following,
    Code (CSharp):
    1.     delegate.connection = [NSURLConnection connectionWithRequest:request delegate:delegate];
    2.  
    for the two parts described in the diff.

    BTW, the latest 5.1.3p1 release seems to have this fix already (though the release note doesn't say anything) so we should give it a try.

    Same here. I wonder if it crashes with other plugins. It happened often when inapp-purchase was sending/receiving data.

    Is there a good alternative solution to WWW please?

    Thanks for the tips on this post. For me, game crashes on iOS when using WWW. I was able to move on from the issue following a tip on another post. I added -fobjc-arc to the file WWWConnection.mm in the Build Phases tab in Xcode.

    I can confirm that Tehelee's fix works.
    Adding
    Code (csharp):
    1. yield returnnew WaitForEndOfFrame();
    Solved the problem.
    I'm using Unity 5.1.3

    I am still getting this exception for over 6 months now from Unity 5.x - Unity 5.4.2,
    has anyone been able to fix it?

    @ntroncos, where are you suggesting to yield a frame?

    Same here.. I had hoped that 5.4.1 and 5.4.2 would solve the problem. Apparently, still happening. I don't know if it's a good thing, but my team can reproduce this really easy on iOS. We just simulate the Very Bad Connection setting via

    Settings -> Developer -> (NETWORK LINK CONDITIONER) Status -> (CHOOSE A PROFILE) Very Bad Network

    Then toggle on this setting by setting 'Enable' to on.

    When firing up our game from XCode, we run into this crash. I think it also helps that our game is online-only.

    Hi all,
    I will be taking a look at this and try to have it resolved an in a patch in the next couple of weeks. If I find a solution that is localized to the WWWConnection.mm I will post a patch here for you to use. Thanks for all of the information you have posted.
    Cheers,
    Chris

    Hi all,
    We were able to narrow down the issue and come up with a resolution. Please replace your current WWWConnection.mm file with the one in the attached zip file. Please let me know if you are still running into issues with these changes. These changes will be going into a patch release soon.
    Cheers,
    Chris

    Hey @InOrbit,
    It looks like it will go into 5.3.7 p3 and 5.4.3 p2.
    5.3.7 p3 will be released on Dec 7th
    5.4.3 p2 will be released on Nov 30th

    I do not know of the issue on android. Do you have a bug filed for it? If not, please file a bug with a reproduction case and/or crash log and post the case number here.

    Cheers,
    Chris

    Hmm. I released an update yesterday including your WWWConnection.mm changes, and I still see a crash. Unfortunately I can't repro this locally, but this appears to be the same issue?

    Hey all,
    After I posted here, I realized that there is a more fundamental issue. There is a fix that is being tested and will be released soon. Unfortunately it was code outside of the Trampoline project, so I cannot share the code here. I will update this thread when I know exactly which patch release the fix is going into.
    Cheers,
    Chris

    Hey @InOrbit, It looks like I will have my PRs in flight by today. So it should make it for the next 5.3 and 5.4 patch releases. As I stated earlier, I will update this thread once I know for sure when this will be released.
    Cheers,
    Chris

    Hi Chris. 5.4.3p3 came out on the 7th - I assume your fixes were not included. Is that correct?

    Hi @Trustrix,
    The fix went into 5.5.0p2. So if you are on f3, you will not have it.
    Cheers,
    Chris

    Do you have a reproduction case and the stack trace? Can you file a bug and post the case number here?
    Cheers,

    Hi @Trustrix,
    Which version of unity are you using? And could you file a bug with your reproduction case, then post the case number here so I can take a look.
    Cheers,
    Chris

    You could manually destroy texture2d object using Destroy(_texture2d) whenever image goes out of scope. This will fix your first approach.

    Hi @AppxploreF,
    The fix went into 5.5.0p2. So if you are on 5.5.0p4, you should have the fix.
    Cheers,

    I'm getting this issue on the latest 5.6.0f3 personal.

    I have a different call stack - and my App doesn't use the WWW class directly - but does use Application.OpenURL() in it's about screen. I do not use network/ads/in app purchases in my app except for a 'find us on Facebook/follow in twitter button'. I don't even currently detect reachability.

    I wish I could copy+paste the call stack, but there's no option! - So here's a screenshot. My app is VSS (Very Simple Solitaire). 20% of iPads also crashing.

    Hi @GilesDMiddleton,
    Is there any chance you could get the full crash log? I would like to see what thread 0 is doing as well as any other threads. Could you also file a bug, as I believe we thought this bug was fixed in a patch release. I looks like it might have regressed.
    Cheers,
    Chris
