Hi, I tried to find some free time to investigate a little bit further in what exactly triggers the crash to happen. A few days ago I had the idea of getting a GL context through GLUT and don't use SDL at all. So I quickly investigated whether this would also crash. So I fetched the cube example (cube.c) from the OpenGL example archive:
https://www.opengl.org/archives/resources/code/samples/glut_examples/examples/examples.html and compiled it through guix. You can find the exact procedure by inspecting the log attached. If I did not make an error this should proof that the problem lies in OpenGL and not in SDL. Tim.
