[PD-dev] gdb listening to PD

[Miller Puckette]

Oops, I should have explained more carefully... I can't get GDB
to load symbols from externs.  So I can trap into GDB when something
goes wrong but then can't see anything.

I usually just compile the object I'm debugging into Pd itself to fix
this.

cheers
