Reproduction steps:
1. Create a new or open any project.
2. Set the Target SDK to 'Simuator SDK' in the Player Settings.
3. Build the project for iOS.
4. Run the project.
5. Attach Instruments to the process with any template.
- The app crashes as soon as the Instruments are attached.
- "ibGLImage.dylib`void glgConvertTo_32<GLGConverter_ABGR8_ARGB8, (GLGMemory)2>(GLGOperationRec const*, GLDPixelModeRec const*)"
- Stack trace attached in the edit.

RESOLUTION: Not reproducible
The original issue is no longer reproducible on Xcode 8.3.2. It's possible to run the app and attach instruments to it. Unfortunately it's not possible to profile the app by using Product->Profile button in Xcode. The issue is caused by the profiler attaching too early and exhibiting some bug in iOS Simulator runtime. This separate issue will not be fixed because it is caused by iOS bug, there's not much we can do about it and it affects very few users.
