--- Comment #10 from Tobias Droste tdroste@gmx.de --- It's not a mesa change that caused this.
I have the same problem with Hawaii. The first time I saw this I tried an older version of mesa which worked a day before and the problem was still there.
I can't say which change in llvm caused this, because I'm only building mesa on my own and receive a prebuilt llvm copy from a repository.
I can upload a backtrace as well if you want, but the segfault I see also happens in SlotIndex::getIndex().
