Details of Segmentation Fault

I am trying to get the details of a segmentation fault that I'm
encountering when running a function from the pgRouting library. The log
in /var/log/postgresql doesn't give me a lot of detail:

2012-09-09 21:03:36 EDT LOG: server process (PID 20008) was terminated by
signal 11: Segmentation fault
2012-09-09 21:03:36 EDT LOG: terminating any other active server processes
2012-09-09 21:03:36 EDT WARNING: terminating connection because of crash
of another server process
2012-09-09 21:03:36 EDT DETAIL: The postmaster has commanded this server
process to roll back the current transaction and exit, because another
server process exited abnormally and possibly corrupted shared memory.
2012-09-09 21:03:36 EDT HINT: In a moment you should be able to reconnect
to the database and repeat your command.

... etc.

Is there any other place to check that would give me a better idea of what
happened?

Thanks!
