             Bug #: 42908
           Summary: r600g: glx-shader-sharing causes segfault
    Classification: Unclassified
           Product: Mesa
           Version: git
          Platform: Other
        OS/Version: All
            Status: NEW
          Severity: normal
          Priority: medium
         Component: Drivers/Gallium/r600
        AssignedTo: dri-devel at lists.freedesktop.org

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.
