gdb is an external tool for me most of the time. :-)

It's what I use for lookup anyway (usually I'll want more context), I
just mentioned addr2line as an alternative.  Either one beats looking
at the map file (why?).

I usually don't even have a BDI hooked up. :-P

I've done breakpoint/step debugging.  Sometimes it's the right tool.
Usually printf works better for me, particularly if there's overhead
to setting up a debugger.

I can still hope. :-)

Weak functions are not a good substitute.
