Just happened so I am still collecting information but ...

having a conf file with nothing much specified but:

...
interface=eth2
dhcp-range=fd00:ff:11::2,ra-only
...

results in a segfault

I got this on real hardware with libvirt but have been able to duplicate 
it virtually.  Attached are the syslog messages from the guests syslog.

dnsmasq 2.65-4 on Fedora 18.
