Re: debugging dynamically linked modules

Ah, I see. I usually do the following: put a break on main and on
scm_error. In addition to getting me back into gdb when an error
happens, it also allows me to go back whenever I need to, simply by
evaluating `(error)'. Of course any other function will do
(`scm_logand' is also a good choice).

This can be used in the following way: set breakpoints, start guile,
load your module, get back into gdb, put a breakpoint in your module
and either go back to guile with `continue' or restart the process
with `run'. Gdb will remember the library breakpoint.
