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:
<a href="https://lists.freedesktop.org/archives/mesa-dev/2016-April/114614.html">https://lists.freedesktop.org/archives/mesa-dev/2016-April/114614.html</a>
And a Piglit patch that tests for the non-conforming behavior that led to this
crash:
<a href="https://lists.freedesktop.org/archives/mesa-dev/2016-April/114613.html">https://lists.freedesktop.org/archives/mesa-dev/2016-April/114613.html</a>
Thanks to Karol Herbst's mesa-dev post, linked from <a href="show_bug.cgi?id=93551#c7">comment #7</a>, 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.</pre>
