No, if it happens that early during parsing there shouldn't be a memory
problem.

Hmm, this hole issue is very strange. Parsing has nothing to do with any
Macintosh specific code and there is no code that specifically interacts
with CDs or any other media.  It might be that you have an invalid path set
to search for include files. The Mac OS sometimes has strange ideas on where
to search for files. Does the bug appear if the CD is inserted before you
start rendering?
It would be great if you could create a simple source file to reproduce the
problem. Please send the file along with a bug-report form (in the
documentation folder) to mac### [at] povrayorg.
