I have a feeling I sent you down the wrong path. This is a problem I am
investigating. The basic issue is that any dlclose() causes a crash with
newer GCC compilers() - 4.x I think.

Can you check pcstub.c & let me know if one of the dlclose() calls is
commented out ? 

I unintentionally checked in such a change to pcstub.c. Generally this
problem manifests as a crash at pcSystemInitialize().

Yes. That will get us to some more points of benchmarking :-)
