            Bug ID: 102337
           Summary: Full system crash when running a custom OpenGL 4.3

I wrote a custom graphic engine as a school project and tested it on different
platforms; it works everywhere (both nVidia and AMD) with binary drivers but
triggers a whole system crash (only the mouse cursor remains responsive) on
MESA + Nouveau.

I am testing it with Ubuntu 17.10 daily build (kernel version 4.12) that
supports OpenGL 4.3 (which is required) on my nVidia card, a GT 740. The full
source code is available at https://github.com/TheBrokenGod/OmegaEngine and
includes a makefile for simple compilation. 

The engine executes some complicated shaders (contained in Source.cpp) in order
to allow order-independent transparency through linked lists of fragments.
