No luck with this. Per that URL, I've put the btraceback.gdb file in the
same directory as the bacula-fd executable on the client (in this case,
/usr/local/sbin) and made the .gdb file executable.

At run time it produces this error:

/usr/local/sbin/btraceback.gdb:1: Error in sourced command file:
No symbol table is loaded.  Use the "file" command.

That's problem 1. Problem 2 is that the syntax given for capturing
STDERR and STDOUT -- 2>\&1 -- doesn't work on either csh (root's default
on FreeBSD) or bash.

Any ideas on remedying either issue?

Thanks.
