What is do-lookup.h and why is it crashing me?

I recently discovered a serious problem with an openGL 3-d program I’m writing called Tronimation. For some reason, it’s as if something I have no idea about is just randomly corrupting the internal state of GLUT and then causing it to crash when unrelated actions are taken. Here is a gdb session. All I did was move my program camera back in Z a bit, and then tried to change the window size. The program siezed, and gave me the same warning: Something to do with glXwaitX, the variable “scope,” and do-lookup.h. Note that this crash does NOT happen if I don’t try to move the camera. I’ve been going through all my source making sure everything is casted to exactly what all the GL/GLU/GLUT functions expect, with no impact on the problem at all (???). What on earth is going on?

Program terminated with signal SIGSEGV, Segmentation fault.
The program no longer exists.

do-lookup.h is a header file that is related to the gcc and the ELF executable format, if I am not mistaken.

Looks like some serious error though, you may want to post this in the linux section to get a more thorough answer.
