Gdb output after using glxinfo

R600g crashes while I try to use LLVM support in it.
LLVM: 1:3.4~svn194296-1~exp1
Mesa: e7a5905d8a3960b0981750f8131e3af9acbfcdb8

Error message before segfault:
0x6af6c0: i32 = GlobalAddress<<4 x float> (i32)* @llvm.R600.interp.const> 0
[ORD=1]

Even running glxinfo causes this error.

Tried LLVM version 1:3.4~svn194202-1~exp1 and it have the same problem, and I
think it worked with an older Mesa. Will bisect Mesa in the future.
