Hi Performers,

Help! I'm trying the latest Performer 3.1 Beta on Linux (RH 8) but my
application now crashes whenever it runs multiprocess. It always appears to
be the CULL process. Even the example programs, e.g. "complex" which I just
recompile, have the same behaviour.

Strangely, the precompiled 'perfly' demo program _does_ run in MP mode but
hangs for a few seconds displaying the OpenGL Performer twirling banner. This
does not happen in single process mode.

Debug sessions with gdb indicate the crash is in pfMemory::ref(void*) but I
have so far been unable to get a full stack trace. (First attempts had the
process stop on real-time signal SIG32 in pthread_getconcurrency but this
just would seem to be gdb being cautious and can be overriden so the signal
is passed on to the Performer process.)

I'm running on a dual CPU PC with Nvidia Quadro4 but same behaviour with or
without SMP kernel, with or without POSIX timers patch, and with the latest
Nvidia driver.

Anybody else having similar problems?

Regards, Simon
