Missed the early part of this particular discussion, but just an fyi, in case
it's of help :
With self-built ODS2/head, I'd seen segfaults in libc on launch as well, for
both signerd/enforcerd.
I never got as far as GDB -- logs showed my issue, wrong/changed perms on the
PID dir, e.g.

and similar for enforcerd.
For my
cat /etc/systemd/system/ods-signer.service
...
[Service]
Type=forking
PIDFile=/var/run/opendnssec/signerd.pid
...
cat /etc/systemd/system/ods-enforcer.service
...
[Service]
Type=forking
PIDFile=/var/run/opendnssec/enforcerd.pid
...
I'd manually created, chmod'd & chown'd the pid dir, but at some point
something (maybe me, inadvertently?) had changed the perms :-/
Simple fix
cat /etc/tmpfiles.d/opendnssec.conf
...
+ D /var/run/opendnssec 0755 opendnssec opendnssec -
...
systemd-tmpfiles --create /etc/tmpfiles.d/opendnssec.conf
worked around the problem here.
I say workaround, rather than fix, as, of course, segfault-ing for lack of a
PID file/dir is not a sane exit ...
