The DJGPP debug support doesn't work with signals, because the signals 
get to the debugger instead of the debuggee.  Is there any reason that it 
should be different with your program?

I'd suggest to set the x87 so that it doesn't generate FP exceptions.  
then you could at least debug the program.
