Subject: gpp crash

I have a 486/33 Mhz clone running DOS 5.0, with 4 MB RAM total,
and using QEMM emm386 as Memory-Manager for EMS, XMS, and to load drivers in
the Upper Memory Region from 640k to 1M.
When I have loaded too much programs in the Upper Memory Region (I tried
one by one and do not know the exakt limit and the critical address where
something happens), starting gcc results in a warmboot of my system
automatically after a few seconds (I do not press CTRL-ALT-DEL!).

XMS-shortage is not the reason, because I can use a 1 MB ram disk with
gcc without trouble.

Did someone else encounter similar problems. Is there perhaps a region in
A0000h to FFFFFh which must be protected from loading drivers etc. there
in order to make gcc run ?

The facit is: I can avoid the problem, but I would like to know the cause
of trouble, and report it to people who have better knowledge of the inner
workings of go32 to make locate (and correct ? :-) the problem.

Greetings,  Nils!
