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

            Status: NEW
          Severity: critical
          Priority: medium
         Component: Drivers/DRI/nouveau
          Assignee: nouveau at lists.freedesktop.org

glxinfo output

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.

A few things:

1. Does the engine do threaded GL calls? If so, nouveau will crash and burn.
2. Does this still happen with the latest code from mesa git?
3. Can you see what's in dmesg when things go south? (Perhaps by ssh'ing
in or
using netconsole, depending on how bad things get.)

1. I make no use of threads; I don't know for sure if GLFW does it with
OpenGL
but I don't think so.

2. I am using Ubuntu 17.10 as LiveCD, unfortunately I cannot install it to hard
drive and recompile MESA, plus I wouldn't know how to do it ;) However the
included version should be very recent.

You can try a more up-to-date stack from https://nouveau.pmoreau.org/

Your dmesg does not include any errors, which is surprising given that the
system hangs. Can happen though.

What are the steps to reproduce this? (i.e. how does one operate your program)

I tried the 08/21 image but I'm having trouble installing the needed
packages.
I managed to install and run LXDE but when trying to install the rest it says
there is no enough space, which is strange because with 8GB of RAM there should
be plenty of it. Unfortunately I have no free partition on which perform the
installation.

Anyway, it is very simple to reproduce the problem:

1) Download the whole project from https://github.com/TheBrokenGod/OmegaEngine
and unzip it
2) Install the following packages and libraries: make, g++, glfw, glew, assimp,
freeimage
3) Run 'make -f makefile' in the root directory of the project
4) Launch the test scene with './omega Scene/scene.dae'
