I got this on real hardware with libvirt but have been able to

dnsmasq 2.65-4 on Fedora 18.

I just fed exactly those options into 2.65 as released by me, and it
didn't crash, so we're going to have to pin this down a bit more.
It would be too easy to be that repeatable. I will set something up
to be simple and yet demonstrate the failure.
More data. I took the dnsmasq.conf file that I used with libvirt and
simplified it even further. Attached the simplified file and the output
from ip addr.
I tried other options: static, ra-stateless, and slaac worked OK (at
least did not segfault). Both ra-only and ra-names segfaulted.
The system is Fedora 18 which is more or less "current". I also tried
Fedora 17 but it only had 2.64 and 2.65 (or 2.59 which did not work at all).
OK, ran it from the command line to get (a lot) more info. This is now
in bugzilla:
https://bugzilla.redhat.com/show_bug.cgi?id=920300
I have not really look at the info yet, just doing the collection.
