Yes.

Trying to do that, but I have no idea what I'm doing with gdb. The
following doesn't seem to do anything useful. It does seem to run an
emacs process, but there's no window that comes up for me to interact
with and nothing else seems to happen:
```

I've also tried with `-nw` with similar results.

Am I going to have to build with debug symbols to do anything useful?
I can try to figure that out, but that's not something that I've done
either.
