Bug ID: 85199
Summary: glxinfo segfaults when mesa was compiled with clang &

strace glxinfo
1)
$ glxinfo
name of display: :0
Segmentation fault
2)
$ glxinfo -i
name of display: :0
X Error of failed request: BadValue (integer parameter out of range for
operation)
Major opcode of failed request: 154 (GLX)
Minor opcode of failed request: 24 (X_GLXCreateNewContext)
Value in failed request: 0x0
Serial number of failed request: 40
Current serial number in output stream: 43
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.
