Hello!
    I've just downloaded & installed MegaPov 0.1, and while I was
rendering some of the demos the program crashed.
    The crash can be reproduced, at least on this machine.  Render
media/minipatch test.pov (from the demos provided), and the program
crashes with "Exception: access violation 0xc0000005, Address:
0x0043bbda".
    I'm running WinNt 4 sp5 on a Celeron 300A, 128Mb ram.
    I hope that this is of some help.

    Best Regards
    Luciano

P.S. Remove the <remove this> from my email address before replying.

I can verify this to some extent. I received the following page fault rendering
the scene in question. Unfortunately I cannot get the program to fault for every
render and it seem to happen sporadically.

MEGAPOV caused an invalid page fault in
module MEGAPOV.EXE at 015f:0043bbda.

Mine also crashes on media. As you would suppose, I went directly to trying
to render my Arda scene and it crashes when starting the render of the type
3 media. I have not tried it with other types.

This might be related to the media bug I found. CodeWarrior caught the 
error and refused to compile it, but other compilers might not have.

Media method 3 will cause this crash.  This is the bug that Chris Huff
pointed out.  Look for an update soon.

And for those with the source to fix the bug I think.. (since i
haven't tested it but it hasn't crashed yet, nathan this look
good?)

in line 474 of media.c change

IMEDIA *AA_Search_Media=Media_List;

to
IMEDIA *AA_Search_Media=*Media_List;

gcc gave me a 
../media.c: In function `Simulate_Media':
../media.c:474: warning: initialization from incompatible pointer type
but it compiled anyway heh.


BTW.. it gives alot of static followed by not static warnings
on tokenize.c
