Please post some actual sample code that demonstrates this problem. 
Most of the cases of variables overwriting each other I can think of in
actual programming deal with pointers, out-of-bounds array accesses,
stack overflows, invalid typecasts ( (int) A = 45, for example ), or
calls to scanf() that use incorrect format specifiers.  In C++, I might
add that reference-type variables can overwrite each other, but that's
why they're there in the first place.  The only way we could tell would
be to have some sample code we could test ourselves.

One other possibility could be bugs in PGCC which are not within the
scope of the DJGPP discussion group.  PGCC is an independently-supported
project and there is a mailing list, AFAIK, which should be listed in
the documentation.  If you think your problem may have something to do
with PGCC, try looking on their list of known bugs and if you don't see
anything, submit your own query or bug report.

hth!
