Hi,

I just installed DJGPP2.0 (binaries) on my Dos6.2/Win3.1
system and was able to compile/link/etc... but when I
runned GDB to debug the programs it gives segfaults.
Eg compiling this program:

#include <stdio.h>
int main () {
  printf ("I am in the main-function\n");
  return (0);
}

with
 djgpp -g -o foo foo.c
and running
 gdb foo

(gdb) break main
Breakpoint 1 at foo.c:3
(gdb) run

will stop at line 3 but gives an SEGMENTATION FAULT
(that is: gdb does not crash but says the program will
cause a segfault at that position). If I don't put any
breakpoints it will run without problems.
(sorry I can't give the correct error, because I am not
at home now)

Did I forget to install something? Am I missing
something? I read the faq, but didn't find anything.
Maybe I should use another debugger (though I am
very familiar with GDB because I use it at work on a
UNIX machine) ? Any suggestions?

Thanks,
Robrecht
