This is a known problem with no good solution at the moment: you
cannot debug programs which hook the keyboard interrupt.  See section
12.10 for the list of gotchas, including this one.

The next release of DJGPP should have some of these problems solved,
including the keyboard interrupt ones.  But for the moment, you will
need to find other solutions, like printf debugging, log files etc.

Is that a graphics program?  If so, it probably doesn't freeze, it
just doesn't display the debugger screen, because you need to be in
text mode to see it.

Try RHIDE or RHGDB, I think they support graphics programs better.
