I'm pretty sure that this is fixed in the current code.

It is indeed fixed in git! But distributions (including Ubuntu and
Arch) are still distributing a vulnerable version and are probably
unaware of it. Could you please apply for a CVE ID (if it doesn't
already exist) so that they fix their packages?

A CVE ID? For a crash caused by a specific local name record which
clashes with the public one? What's the vulnerability or exposure here?

This is actually crashable by querying any CNAME that points to localhost.localdomain, given that upstream is 8.8.8.8, because localhost.localdomain nearly universally exists in /etc/hosts as ::1, and 8.8.8.8 doesn't have an AAAA entry for it. So this is a security issue.
