Segmentation fault in @kmamal/gl #57

Open joepie91 opened 3 months ago

joepie91 commented 3 months ago

(Opening this issue here because I'm using it with @kmamal/sdl, and with the gl repo being a fork, it has issues disabled, probably unintentionally?)

My process just segfaulted after a GLSL compilation error; this may very possibly be caused by my somewhat janky hot-reloading setup, but I was unable to determine this from the stacktrace, so I'm posting the stacktrace here in case it's a gl bug.

The error output in terminal:
