Logger - core dump

[Mike via freebsd-questions]

FreeBSD 13.0 amd64

logger has been doing a core dump multiple times a day...

# lldb -c logger.core -- logger
(lldb) target create "logger" --core "logger.core"
Core file '/usr/local/var/opendnssec/signer/logger.core' (x86_64) was
loaded.

It occurs when the opendnssec signerd program calls a script (written
for /bin/sh) after a zone has been signed. The script has calls to
logger to track the status of various operations.

It is during those calls that logger dumps core.

This has started occurring since I upgraded from 12.2p6 to 13.0. Also
during that upgrade, the opendnssec package went from 2.1.8 to 2.1.9. (I
would have been happier if only one thing had changed, but can't change
that now... :) )

I see the logger core dumps only when called by the opendsnsec signerd
program, as described above.

I do not know what to do next...
