GDB ouput for the crash

I'm currently trying to find the Piglit test (it's one of the GLX tests run by r600.tests), that causes screen corruption. In the process I hit a segfault in r600_dri.so, which I can cause repeatedly with glx-shader-sharing.

Used stack:
Mesa: Git/9ae10e9c
libdrm: 2.4.27-1
Kernel: 3.1.1
X.org: 1.11.1.902-1

The attachment shows a backtrace and a register dump. Let me know, if you need more.

Sorry for the noise, seems appending "-auto" to the invocation fixes this.
