Looks like a mac driver bug. glEndTransformFeedback_Exec is a driver function. I will try to repro and file a radar.

Does not repro on my machine. I think users are very unlikely to hit this given how rare transform feedback is, and impact of a GPU process crash is low as it will restart seamlessly. Lowering priority.
