I am having problems reminiscient of the nb_clean() kind. I am loading a
vrml scene into performer, and then bufferAddChild() all the respective
inlines, with a corresponding pfBuffer::merge() after each addChild. The
other suggestion of having a bounding sphere didnt work. The app runs
almost all the time, except when I give demos :-). And I get the following
in debugger when examining the core file.

Core from signal SIGSEGV: Segmentation violation
pfGroup::nb_cull(<stripped>) ["pfGroup.C":258, 0x5d47de14]

Thanks
Swami
