Shaders: Blur shader causes editor crash

I will try and explain my problem as best I can. There is something odd happening with shaders/materials in the 2017beta and it is more or less directly linked to blur shaders. I'm not sure what technique different blur shaders use but I've tested a blur shader called Gaussian Blur and the blur shader that is included in PRISM and they both make the Unity editor crash when you try to....

• Preview them on a material.
• Assign the material containing the shader onto any object.

This only happens with the aforementioned 'blur' shaders while other shaders work fine, I will also attach the crash logs/dump files in case it might help. Does anyone have any clue what might cause this?

Spoiler: Selecting the material with a blur shader applied to it in project view results in an editor crash

Spoiler: Assigning the material to a component also causes an editor crash

 

The editor should never crash, thus I'd submit a bug-report following the advice in this document. Don't miss to post the bug-report Case number that you receive here as well, so Unity can pick up your report faster.
