Hello,
in a quick look at the trace and the code, the assignment with empty
value seems to be the issue, likely to be:
$rU = $dbr(ra=>[0,1]);
I remember that a similar issue was fixed long time ago, but not sure
before your version (3.2.x) which is very old right now. If you have
time, you can simulate the same situation using a more recent version
such as 4.2 or 4.3.
Being traveling, I can't do much testing and analysis of the commit logs
to see what and when was fixed.
For the moment, you can try to catch the situation in the config:
if($dbr(ra=>[0,1])!="") $rU = $dbr(ra=>[0,1]);
Cheers,
Daniel

How do you load the value of fwdnumber and then how you use it to
update the request uri?
The backtrace points to an assignment, but I need to know exactly the
operations you do to track it down.
Cheers,
Daniel

I see now that we had an entry in the ‘subscriber’ table with
forwarding enabled but the ‘fwdnumber’ field was blank.
Could this be the cause?

according to the log, you got a coredump:

Send the output of 'bt full' taken with gdb from the core file --
