Hmm... 0x0f00115e doesn't look like an address in a DJGPP program.
Can you load the program into GDB, like this:

    gdb foo.exe

and then type "disassmble 0x0f00115e", and see whether GDB finds that
address in the program?

If the bug in the debuggee is hard enough, it could conceivably crash
the debugger as well, especially when the debuggee hooks hardware
interrupts.  It's not unheard of.
