Please direct responses to DIXON@UCRPH0.UCR.EDU, as I do not subscribe to
this group.

Problem: I am trying to dynamically allocate a modest (32k) area of memory.
It seems to allocate OK, but corrupts the heap when I deallocate, hence
things go haywire when main() is exited.  I've tried every stinking
combination of memory model and pointer type I can think of.  The only
thing that seems to keep the machine happy is if I allocate very little
space.

Anybody have any suggestions?  I'm programming under Borland C, on a
386 with 4 M.  I've got QEMM386 running for memory management.  Using this
program shows lots and LOTS of free RAM, yet I'm getting all of this
erratic behavior.  Thanks.

					Dave
