This would seem to affect all Intel platforms, right? kbr, can you please take a look or reassign to a better person? Thanks.

This is a crash inside the old copy of Mesa that we are currently using for testing purposes. It's impractical for us to investigate and try to patch bugs in it.

We're working on replacing it with SwiftShader, at which point we'll start actively looking into bugs like this one if they are actually provoked inside SwiftShader.
