Backtrace vulkan_intel.so

I reported in the author https://github.com/Novum/vkQuake/issues/46

He said is very likely intel driver bug 

Code source from 
git clone https://github.com/Novum/vkQuake.git

Dependences gcc libsdl2-dev libvulkan-dev libvorbis-dev libmad0-dev

Make file is in Quake/

cd Quake/


Run ./quakespasm (Need files pak0.pak and pak01.pak in Quake/id1/ directory.

Running fine but has some problem when change choose resolution or any option
in the menu and click in test or apply options segment fault

With old xcb has problem with xcb_wait_for_special_event 

With latest xcb code reported 

quakespasm" received signal SIGSEGV, Segmentation fault.
get_special_event (c=0x19d4c70, se=0x1da0340) at xcb_in.c:755
755 if (!(se->events = events->next))

Or Backtrace added in attachment related with vulkan_intel.so

And rarely case backtrace report ..
