I'm running the unofficial compile of RC2 for Mac 64 bit on a Intel Core 2 Duo
running Mac OS X 10.5.8 (4gb of RAM).

I have a file "scherk.pov" which includes a large (about 6 mb) scene file that
was generated by Mathematica.  Scherk.pov is set to load a different file for
each value of the clock (so I'm using animation).  In scherk.pov, there is a
nested while loop.  If the size of these two loops is 4 and 2 (outer and inner),
then the scenes compile fine and the clock works normally.  If the size of these
two loops is 5 and 2, then the first scene compiles fine, and the second scene
fails to compile (the message reported is that the operation timed out).  If I
render again, I get the error "Parse Error: Cannot open input file." If I push
render again, the first frame renders fine.

I see that this error has been reported before, for example:

http://news.povray.org/povray.beta-test/thread/%3C4c4ad593@news.povray.org%3E/

and

http://news.povray.org/povray.windows/thread/%3Cweb.4cf1c24e963f566b53793d520@news.povray.org%3E/

On my laptop (Mac OS X 10.6.6, Intel Core i5, 4gb ram),  the 5 and 2 loops run
fine once; then I get the parse error if I try to rerender.

I looked in the bug tracker but wasn't able to find any relevant bugs.

Shall I file a bug report, or are there some troubleshooting things I should try
first?  Am I simply asking too much of POVRay?  (There are 1967735 finite
objects in the scene --- is that too much? I'm pretty sure I've rendered include
files much bigger than this before, but I've never used while loops much
before.)

Thanks,

Adam

After upgrading to RC2 and a new laptop (i7 and 8 Gig Ram). The scene 
that was giving me problems now renders OK on successive renders.
