 Issue 739678  has been merged into this issue.

Many of these fuzzer issues seem to be happening in the mac software rasterizer. I think I would like to double-check that they are actual bugs in there, as opposed to a bug in command buffer that leads to potential security issues, which are normally invisible to the instrumentation as they would happen on the GPU, but suddenly become visible when running in a pure software implementation.

I've meant to spend some time on at least one of them to get a better idea, but haven't had a chance yet (any taker otherwise welcome).

Re #5, yes that sounds like a good idea.

That said, I'd like to keep aggregating all of the GPU crashes into a single place -- we can quickly sweep them for thinks we think may be actionable from here.

Absolutely, thanks a lot for this!
