Hi guys,

This works:

      pfVec3* verts;
      ushort* ilist;

      gSet->getAttrLists(PFGS_COORD3,(void**)&verts,&ilist);
------------------------------------

      This broken:

      pfVec3* verts=NULL;
      ushort** ilist=NULL;

      gSet->getAttrLists(PFGS_COORD3,(void**)&verts,ilist);

-----------------------------------------------

      So as we all know indexing a NULL pointer on an O2 causes a core dump. the
thing is that "ilist" should NOT be getting used because none of our geometry is
indexed. Anyway, I copied the non-NULL setting code out of a Performer example
and it works. It bugs me, but it works.

Can anyone explain exactly why initializing those pointers to NULL cuases an O2
to shake and convulse?
