I'm new to LWJGL and OpenGL, and I've done some google searching and couldn't seem to find anything else related to this.
I made a basic test program to create a blank window. I can create the window and run the application fine, but if I try to change the clear color using glClearColor()
, the application "crashes."
Here is the text printed in the console:
[error occurred during error reporting (printing problematic frame), id 0xe0000000]
# Failed to write core dump. Core dumps have been disabled. To enable core dumping, try "ulimit -c unlimited" before starting Java again

This is the file that the error created (rather large): https://pastebin.com/9h0gsRmTlink
This is the code:

Any pointers/tips would be helpful.
You are missing
GL.createCapabilities();
From the getting started:
// This line (~the above) is critical for LWJGL's interoperation with GLFW's
// OpenGL context, or any context that is managed externally.
// LWJGL detects the context that is current in the current thread,
// creates the GLCapabilities instance and makes the OpenGL
// bindings available for use.
Also, move glEnable(GL_DEPTH_TEST);
after that line as well.
You do not get a crash now on your machine, but you may with different conditions
