As I recall OpenGL didn't work on Linux for a couple of years for just this reason. Are there any "unrecognised syscall" errors before the crash? Ultimately I suppose the cause doesn't make any difference, all you can do is try and find a way of running the code using different library's, the use of a software renderer sounds like a promising solution.
