Comment # 10 on bug 1205818 from Michael Pujos

vkquake is still crashing for me after compiling (using osc build) libX11-6 and
libX11-xcb1 from X11:XOrg / libX11 , and installing these packages.
I verified in the build output that  --disable-thread-safety-constructor was
present.

It crashes differently now:

vkquake: xcb_in.c:757: xcb_request_check: Assertion `!reply' failed.
Aborted (core dumped):


 #4  0x00007f9e26413c46 __assert_fail (libc.so.6 + 0x35c46)
 #5  0x00007f9e2606b478 xcb_request_check (libxcb.so.1 + 0x10478)

 #7  0x00007f9e1bdac3f7 n/a (libvulkan_intel.so + 0x1ac3f7)



Although I had also seen this crash previously, along with the
xcb_xlib_threads_sequence_lost one.
