Why should it have to? Where else is it going to stop, in a variable?
Don't the ()'s even give you a small hint?

Yep. Try compiling with -g to get debugging information into your program 
before bitching about useless the debugger is. This is in the gcc man page
as well as the gdb info stuff. If you don't give the debugger anything to
work with, don't go expecting it to cooperate much with you.
