Comment # 10
on bug 93551
from Jamey Sharp
(In reply to smidjar2.reg from comment #6) > I disassembled ApplyConstants() where the game crashes when using OpenGL > override to 4.2. I spent a while poking at this crash in gdb, and I was definitely seeing the same segfault at the same instruction and call-stack. I've sent a (one-line!) patch to mesa-dev that fixes this segfault on startup: https://lists.freedesktop.org/archives/mesa-dev/2016-April/114614.html And a Piglit patch that tests for the non-conforming behavior that led to this crash: https://lists.freedesktop.org/archives/mesa-dev/2016-April/114613.html Thanks to Karol Herbst's mesa-dev post, linked from comment #7, for pointing me in the right direction to find this Mesa bug. Granted, the game developers ought to check for errors returned from glLinkProgram and fail more gracefully than a segfault, but I doubt we're going to get them to do *that*... I can now play this game somewhat successfully on i965 with MESA_GL_VERSION_OVERRIDE=4.2. There are still plenty of rendering bugs I haven't dug into yet, but I played for an hour without crashes, at least! I don't have (or particularly want) a commit bit on Mesa or Piglit, so now we need somebody to review and hopefully merge these patches.
