Me again.  I've broken my compression proggy again by trying to add
another feature.  This time, I've managed to get it to give me
a "General Protection Fault" when I try to do a new.  This is under
straight DOS, by the way.

I'm building a huge (about 8000ish or so) linked list of objects (16
bytes per object, not including allocation overhead) for the purpose of
sorting a huge list of files.  When I'm getting towards the end of the
list of files, I get a GPF when I try to create another linked list
object.

I've tried making the stack bigger (a-la FAQ 15.9).  I've tried
increasing the CWSDPMI heap size (a-la FAQ 15.4).  Neither seems to
have helped.  Whether I'm debugging the program under RHIDE or just
running it straight, it seems to fail with the exact same error, in the
exact same spot, on the exact same file, every time.

The GPF gives me esi=00000010, meaning that my stack has somehow
wrapped around.  Right?  But how is that possible if I've increased the
stack size?  What else could be causing this problem?
