Nice! Thanks for the detailed explanation, Russ.
Fortunately, I didn't have to worry about going very
deep. As soon as Presotto noticed that the problem
was a *user* overflow, I went back through my code.

Sure enough, the problem was that I was moving a
block of memory, but based on the strlen(), not the
strlen() plus the terminating null. My logic fumbled
somewhere through the recursion.

On the bright side, my preprocessor is finished *yay*.

Thanks for the help, as always, guys.
