Physics.OverlapSphereNonAlloc throws System.AcessViolationException

yo peoples.

Below a very basic script, attached to a game object in a scene with number of box colliders. Run in the editor the script works correctly, drawing a debug line to the detected colliders, and outputing the number of collisions detected to the console.

When I deploy the same scene to the Hololens, I get an exception.

"Attempted to read or write protected memory. This is often an indication that other memory is corrupt."

Any thoughts, suggestions etc would be much appreciated.

Code (CSharp):

1. public class Test : MonoBehaviour {
2.  
3.     private Collider[] overlapResults = new Collider[10];
4.  
5.     public int NumberOfCollisions = 0;
6.  
7.  
8.     // Use this for initialization
9.     void Start () {
10.      
11.     }
12.  
13.     // Update is called once per frame
14.     void Update () {
15.         NumberOfCollisions = Physics.OverlapSphereNonAlloc(transform.position, 10f, overlapResults);
16.  
17.         for (int i = 0; i < NumberOfCollisions; i++)
18.         {
19.             Debug.DrawLine(transform.position, overlapResults[i].transform.position, Color.red);
20.         }
21.  
22.         Debug.Log("collisions " + this.NumberOfCollisions);
23.     }
24. }

 

Thanks for that, the Exception is thrown before the Debug gizmo code on Line 15.

Awesome, thank you will give that a try

 

I can confirm 5.6.1 fixes this error.
