--- Comment #6 from Michel Dänzer michel@daenzer.net --- (In reply to sarnex from comment #5)
I compiled LLVM3.5 debug and Mesa debug, so hopefully there is enough information here. The backtrace is attached.
That's a crash in LLVM. Does that also happen with Mesa commit 54de7099115502c561f5f51095e08dc0a52c71b7? If not, can you test my patch on top of that?
