I am posting this here rather than the Github Issue tracker because I doubt it is actually a bug in glfw, but I would appreciate any help in fixing it.
On this specific PC
glfwTerminate is reliably causing a segfault somewhere in
XCloseDisplay. Output of the
glfwinfo test in gdb:

I am mystified as to the cause of this error, as everything was working fine until recently. It's also strange that all of my code runs fine (creating window, loading OpenGL function pointers, rendering, etc) up until this segfault at the end. Any ideas?
