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.

I finally found that I omitted to specify "--prefix=/usr" on build time. Could this be the source of the crash (eg. if old "includes" were in this place) ? The game didn't crash since many days, I think that was the issue. Now I rebuilt mesa like I was doing before, game crashed again, and I got this error (previously I wasn't launching the game with MESA_DEBUG) : Mesa: User error: GL_INVALID_VALUE in glMapBufferRange(length = -42702)
I finally re-open it since the crash still occurs time to time.
Aehm... Is this still a thing?
I think I haven't seen this bug since some times... though I play less to this game. Closing.
