Mental Ray 3.2 P4 2004-02-25 - By Jim Rothrock

That's a likely place to have a problem that could make the renderer
unstable, since geometry shaders allow access to fundamental renderer data
structures. If the tests I described in my previous message indicate that
the problem is thread-related, and you are using Visual C++, make certain
that the compiler options are set to generate thread-safe code. If the
problem still persists, I suggest commenting out parts of the geometry
shader code until the cause of the problem is isolated.
