I have been having trouble with a compiler project that I am doing in
MS C 5.1.  It appears that malloc() is sometimes getting hung in a very
tight loop.  It doesn't happen all the time.  If I run my program
right after rebooting it always works, but if I run it right after a
compile, sometimes malloc hangs.  If I run it in CodeView and this happens
I can stop it with Ctrl-Break, and step through the machine language,
and it is stuck in the library routine in a very tight (about 6 instructions)
loop.

I am using the compact memory model, on a 386/20, and MS-DOS 4.01.

Just wondering if this is a known bug, or a common programmer error of some
sort?
