This question is not appropriate for the gcc@gcc.gnu.org mailing list,
which is for the developers of gcc.

I really don't know where to ask questions about developing a debugger.

If I were writing a debugger, I would probably just single step until
the debug info indicated that I had entered a different line number.
But that might be too slow.  I don't know what actual debuggers do.
Fortunately you can simply look at the source code for gdb to see what
it does.
