Question:  I've got an asm routine (in NASM) that seems to work
perfectly (I can call it from the main() function with no apparent
problems).  But when I call it from certain contexts (for example from a
member function of a class), I get the following error when stepping
through the statement after the routine:

Program has received signal:
SIGABRT, Aborted

I know that this error is actually a result of calling my routine, since
I can comment out the call to the function, and there's no problem...
So I'm assuming it must be that I messed up within the routine...  I
modify SI, DI, BP, and DS, but I push and pop all these at the beginning
and end...  Is there anything else that I could be screwing up in my
routine that is causing this strange behavior?  I don't have to save the
other general registers, do I?
