I don't know anything about what happens, but I know that this crash happens
only when mesa was compiled with clang (from git) against libc++.
Building clang and mesa against libstdc++ with otherwise the same build config
does not produce the crash.
I originally stumbled upon this issue because kwin was always crashing with
OpenGL enabled.
thx for your time.
