I am hoping someone can help explain a core dumping problem that I am having
when trying to call pfGSetGState() with an in-house geometry loader similar to
the geometry loaders supplied with Performer. I am executing the following
standard geometry loader/builder stuff in the APP process:

   gsetList = pfuMakeGSets(builder);
   for(i = 0; i < pfGetNum(gsetList); i++)
   {
      gset = (pfGeoSet *)pfGet(gsetList,i);
      pfGSetGState(gset, geostate);
      pfAddGSet(geode,gset);
   }

  12 main(0x9, 0x7fffaf1c, 0x1, 0x0, 0x100378a0) ["Main.C":46, 0x478d90]

The geostate being used is one that had been created for another object
during scene initialization. Reusing this geostate in the midst of
pipelined APP, CULL, DRAW rendering seems to be a problem. However, if I
create a NEW geostate along with the NEW geosets my core problem goes away.
What is wrong with the call to pfGSetGState() using the OLD geostate?
Any ideas?

                  Thanks,
