Here is a reply I got in mail to my original plea for help.  It basicaly
concludes that iff.library v16.1 has a bug that trashes the free memory list.

------------------------------------------------------------------------

   You're pretty right on iff.library, it screws up the free memory list.
This happens from time to time, depending on the particular picture. I had
some Brushes and some ILBM with XModem garbage, and one caused a bug similar
to yours, crashing in Avail, the other caused my 2 1/2 mega fast ram to
fragment incredibly. Putting the particular pics through DPaint solved the
problem. 
   I traced the bug to OpenIFF(), that is, if you OpenIFF a picture, you're
sold if it causes trouble, as you have no possible way to check IFFError()
before OpenIFF(), and afterwards it's too late. Certainly not the kind of
bug you'd want in a program where other people will input their pictures!
 
   Bottom Line: the iff.library causes this, be careful.
 
   You're welcome to post this reply, I can't get to post currently - emacs
messes this terminal. Actually, I would like you to post this.

If we could only find out how to contact the iff.library's author...
