[syslog-ng] Syslog-ng v3.5.3 - Core dump from a certain incoming message?

Has anyone seen this or know what may be causing it? When I run a stack
trace, I can see that this host causes syslog-ng to crash every time it
sends a message

I've run a couple of tcpdumps and it *seems* to be caused by an ARP request
from a Cyclades box. This seems very odd to me of course.

10 130.085308 Cyclades_01:be:4b SuperMic_9a:58:be ARP 60 Who has
x.x.188.52?  Tell x.x.188.11

The *only* other packets from that host are repeated so they don't seem to
be the cause:
