           Summary: [r600g] random and reproducible crash in Left 4 Dead 2
                    (bisected)
          Severity: normal
    Classification: Unclassified
                OS: Linux (All)
          Reporter: b.bellec@gmail.com
          Hardware: x86 (IA32)
            Status: NEW
           Version: git
         Component: Drivers/Gallium/r600
           Product: Mesa

Left 4 Dead 2 crash quite randomly, most of the time between 45 minutes and 80
minutes for instance. But sometimes earlier (15 minutes).

When the crash happens, it's always at the same moment in the game: it's in
"Versus Mode" when you play an Infected character. The crash always occurs when
you're in the mode where you can follow the survivors while the spawn counter
is decreasing, and then reaching zero, you go in the POV of your infected
character. The game crash in this transition.

When the game crash, in fact it freeze during 10-15 seconds and then the game
exit with a segfault.

The first bad commit is:
commit: cefa06cd6967f2c2db2acfb54a4bf3be398a3ce8
egl: Add STATIC_ASSERT() macro
author: Chad Versace <chad.versace@linux.intel.com>
date: 2014-03-17 22:39:23 (GMT)

I was quite surprised about this commit but it take me many time to bisect it
given the nature of the crash. And I then take many time to be sure that this
is the first bad commit.

I just try with recent dev mesa (d3c0e236f23e66cb2b4a75f5161282b2d15ff73f) but
the crash still occurs.
