I was able to isolate the worst of the problem. Below is a .POV file that
demonstrates it. I was originally hoping to send the files as attachments,
but due to my situation, I must use the webview of the newsgroups where
that is prohibited. There is one problem with sending the code this way.
You need a gif named Book1.gif. I can provide mine on request with an
email, but I do not believe it is specific to that gif.
Two files are included below. The first is the .ini file I used to create
the animation loop. The second is the .POV.

/*Demonstration of problem:
Here is a scene sample that demonstrates my problem. It is a
bookcase whose book's spines reference GIFs for their texture.
When I render this scene, system memory is gobbled up at an alarming
rate. While I am not expert enough to absolutely absolve myself of fault,
I am confident this is a
legitimate bug since POV does not Red Flag any errors while parsing.
I believe the error to reside in this line:
texture{pigment{image_pattern{gif "Book1.gif"}
In my coding, I have the random number generator pick a random book
spine image, using a #switch structure. Below, I have highlit
the place where this switch can be determined. When the Book_Pattern
varible is set to a legal value or allowed to reference the
random number generator, the bug is invoked. However, when it is
set to 0 (or any other unspecified value), causing the above line
not to be parsed, the undesired behavior does not occour.

I hope having to cut and paste this does not corrupt the file. If
nessesary, I can email any of the above files or results on request.
