| Summary | RS880 + mesa/llvm heads - segfault | mesa +r600 llvm = segfault |
Comment # 1
on bug 63632
from Andy Furniss
I am still getting segfaults with updated mesa/llvm, though the bt is a bit
different.
I can reproduce with a new 64 bit LFS and an old 32 bit one.
Have put RV790 back in this box so it's not just RS880.
Program received signal SIGSEGV, Segmentation fault.
