I posted a message in comp.lang.ada regarding problems running 
a tasking program with gnat3.04(DOS). Unfortunately, I haven't had
any luck with finding solutions to this problem from that group
so I hope I have better luck here(I know this is mostly a C/C++ 
group but please keep reading). When I run the program diners.exe
(one of the examples in the gnat package) I immediately  get the 
following output:

"Cannot continue from exception, exiting due to signal 0123
 Page fault at eip=0001a903, error=0006

When I trace through the program with fsdb it starts working but then
causes an exception at some point. I've experienced this with another
tasking example too.

I don't know if this is related to the above, but after I use 
CWSDPMI for compiling programs, my system hangs when I try running 
Norton Commander. Ofcourse, I now just use EMM386 because of this.

The system I am using is a 386 with 4MB.
