I generated a temporary patch and forwarded it to the email address in
the OpenDMARC Makefile and filed a ticket. I got this response from the
ticket but 1.3.0 is BETA, not RELEASE.

[tickets:#94] core dump in mlfi_eom()

I am getting a core dump in mlfi_eom() under FreeBSD 10.0 where the
OpenDMARC milter is followed by the OpenDKIM milter. According to gdb
(below) dmarcf_findheader() fails to find the header and returns NULL
but the code does not check for that condition.
In my case, OpenDKIM reports:
