I could have followed any instructions geared towards identifying the
cause, but unfortunately, I do not have enough time on my hands at the
moment.
The other person is running inside a jail, while I am not. He says:
1. sysctl kern.sugid_coredump=1  is necessary in FreeBSD for the core
dumps. My system already has that enabled.
2. He used "-glldb and stopped the exim binary being stripped" - and that
is an option passed to gcc. I don't know the equiv for clang.

If you'd like to build a version that would coredump, I am happy to give
you access to my server for that purpose.
