You can get unbound to leave a core in /var/unbound by setting
kern.sugid_coredump=1 .  I found that sometimes (like on a hup and
sometimes when interfaces go up/down) unbound would crash, which I
tracked down to getpwnam() not having a /etc/pwd.db to use in the
chroot.  The latest version of unbound appears to have made a lot of
changes in that particular place, getpwnam() doesn't even appear in that
file anymore.

I submitted a bug report for the crash that I found, I don't know if
it's related to yours.
