I can't reproduce the crash.
I ran compiz under valgrind --trace-children=yes --trace-origin=yes and did the same what I was doing when the crash occured multiple times.
only a couple of uninitialized uses, jumps and free/new mismatches show in the attached log.

Compiz crashes as soon as i enable the OpenGL plugin.

I got a stacktrace with valgrind when it crashed.
