Segfault on SBCL when running examples

[neil-lindquist]

I tried running the demo on SBCL, but it crashed with a memory fault. I'm using Red Hat Enterprise Linux Workstation release 7.4 (Maipo). I also tried the example for trivial-gamekit, but it crashed with the same error.

This is SBCL 1.4.0-1.el7, an implementation of ANSI Common Lisp.

I'm omitting the output of quickload, since it's alot of output as it downloads libraries

Does your machine support X11/OpenGL 3.3? You probably can check with

glxinfo | grep "core profile version"

That's the problem. Thanks
