At Taodyne, we are developing a 3D presentation software called Tao Presentations. It works well on Linux, except with Gallium3D drivers (e.g. under VMware or on systems with software fallback; currently testing on an ATI ES 1000...)

The problem is a crash very early, simply trying to create a GLX context. The stack trace looks like this:

My question is: what precautions should a program using LLVM take to avoid interfering with the LLVM pipe?
