Machine is running 8.6. Latest drivers (though admittedly the CD drive
is a CDR...). The Mac has 64MB of physical memory with Virtual set to
80MB. The OS is using about 16MB, POV has 27MB (so 43 in use total, the
VM should not be an issue) allocated and the death of parsing occurs
whether the POV is currently using 3MB of that or 13MB of that. I've
been keeping an eye on memory since I haven't worked with meshes much
and was concerned 27MB may not be enough... this is happening after a
recent launch of POV i.e. launch, enter key to open the scene file I was
last using (navigation services support is *nice* guys!), command-R,
wait five seconds insert CD (POV using only 1/10 of allocated memory at
this point) after a second or 2 parsing dies as above.

I'll double check that I don't have both Apple's CD driver and the Toast
CD reader running (now at work...).

I've got ZoneRanger wandering around my HDs somewhere if you want more
detailed info on memory usage....

Basically I'm batting 1000 with the bug (whether it be POV or some other
gremlin), the only reason for using a large file (actually the file
isn't large, nor really complex, but math.inc takes a while to generate
a few hundred thousand smooth triangles) is so POV is still parsing when
I insert the CD (though I suppose a trivial but long #while loop would
discount memory being the problem). Again I still think it's related to
the doubly-declared macro given the line that always causes the problem.
I'll write a couple of trivial macros and test it that way...

Have Fun
Martin
