To:	Djgpp-discussion list <DJGPP AT sun DOT soe DOT clarkson DOT edu>

Hi, I noticed the existence of DJGPP a week ago and since I've been
using various Unix machines before, I immediatly took the chance of
being able to compile and test my programs at home.
I got through compiling and running a large bunch of programs without
problems, but two of them crashed shortly after starting them, producing
an segmentation violation error. Tracing with the debugger showed
that after returning from the first subroutine call in main(), the
register %eax has a wrong value, so the next access to main's local
variables gives the segmentation error. I haven't been able to produce
this error with a reasonably small program, so I can't mail the
source to the list. Is there any known (possible) explanation for
this behaviour, maybe some (undocumented) restriction on module size
or something like that. Otherwise I will go on and try to reduce the
program size to get a mailable version of this.

Jens
