I have a fairly complex scene graph which was running just fine until
I added a pfDCS containing a pfGeode with a pfGeoSet whose primitive
type is PFGS_LINES. I want an evenly-spaced grid plane attached to an
object in the scene. Now I get a core dump in pfFrame() -> pfProcess.C
-> malloc.c. See below.

Process 23698: Stopped on signal SIGSEGV: Segmentation violation (default)
_lmalloc(<stripped>) ["malloc.c":754, 0x0f961548]
Process 23698 stopped at ["pfProcess.C":2703, 0x00550a84]
Process 23698 stopped at ["malloc.c":754, 0x0f961548]

I am running Performer 2.0 on a High Impact with IRIX 5.3.

Question(s):
1. What do I need to do to get this to work?
2. Is there something specific regarding the geostate that I should be
   aware of and could this cause the problem?
3. Can anyone point to any simple examples of scene graphs with pfDCS,
   pfGeode, pfGeoSet with PFGS_LINES? I modified the example gset.C in
   /usr/share/Performer/src/pguide/libpr/C++ changing the primitive type
   to PFGS_LINES and it works just fine.
