I've put one of the offending pf commands (pfIsTexFormatted) into
perfly (perfly.c) as a simple test case.

The routine I modified in perfly.c is "loadDetailTextures", and I've
put the comment /* Test */ next to the 2 lines I added. The O2
does not produce a core file when I run this perfly and dies on the
pfIsTexFormatted. If I run this modified version of
perfly on the machine it was compiled on (an IR with IRIX6.2) it works
fine. I haven't got a compiler on the O2 yet, so I haven't been able
to run a modified version of perfly compiled on it.

I get similar behavior if "pfFormatTex" is used. On the other hand,
if I use "pfApplyTex" I get a core file, but unfortunately I don't yet
have a dbx to apply to it yet (i.e. a Dev Option for IRIX6.3).
