Please send me, and just me, not the list, the .ii file generated when
you compile with -save-temps.  I'll see if I can figure anything out
about where the memory is going.  I don't guarantee anything, but I'll
see what I can do.

Again, please be sure not to send the preprocessed source to this
list, since you earlier message indicated that it was quite large.

Thanks,
