Blocko compiles with a ton of warnings, then crashes when run.

[tux314159]

GLGS 4.60, arch linux, gcc 10.1.0. It says 1st chunk generated, ready to start game, and shows the window and I can see what's in it, but then it crashes with: GL CALLBACK: ** GL ERROR ** type = 0x824c, severity = 0x9146, message = GL_INVALID_ENUM in glGetIntegerv(pname=GL_GPU_MEMORY_INFO_TOTAL_AVAILABLE_MEMORY_NVX)

I can't seem to see where the error is with GDB.
