[opendmarc-users] opendmarc crashes

[Steve Siirila]

Juri pointed me in the right direction; the patch he pointed me to seems to
be the issue we're running into.  The problem stems from the fact that a
particular domain (bbsv2.net) has a malformed DMARC record:

_dmarc.bbsv2.net. 156 IN TXT "v=DMARC1\; p=reject\; rua=mailto:
dmarc_agg at dmarc.250ok.net\; ruf=mailto:dmarc_fr at dmarc.250ok.net\;
rf=afrfruf=mailto:dmarc_fr at dmarc.250ok.net\; fo=1\; pct=100\; rf=afrf"

Since this is not the case for most sites, this issue doesn't cause
opendmarc to crash.

To determine whether this patch has been installed or not you can simply
run opendmarc-check to find out:

$ opendmarc-check bbsv2.net
Segmentation fault (core dumped)

The patch that fixes this, as Juri pointed me at, is here
<https://sourceforge.net/p/opendmarc/tickets/227/> (Ticket #227).
