           Summary: WebGL Conformance Test Runner crash
           Product: Mesa
           Version: git
          Platform: Other
               URL: https://cvs.khronos.org/svn/repos/registry/trunk/publi
        OS/Version: All
            Status: NEW

          Severity: normal
          Priority: medium

full backtrace

When running WebGL test runner with r300g there is:
Program received signal SIGSEGV, Segmentation fault.
0x02650ab3 in dri2FlushFrontBuffer (driDrawable=0xb0e91200,
loaderPrivate=0xa2afb020) at dri2_glx.c:460
it doesn't always crash at the same test but it is 100% reproducible when you
click run tests and wait.

This is with 
mesa: d136d1d2e1174d2420ce5e32507904243ab240cd
kernel: 2.6.37
GPU: RV530
Firefox 4.0b8

Firefox must be started with MOZ_GLX_IGNORE_BLACKLIST=1 (acceleration is
disabled by default for mesa because of crashes). You also need to set
webgl.enabled_for_all_sites to true in about:config. I'll try to reproduce this
with some other driver.
