It works if all IPv6 rDNS lookups succeed. Even if most IPv6 rDNS lookups succeed, you might not notice the problem (and that is when it is the most dangerous). The best way to reproduce is to run on a local IPv6 subnet where *none* of the IPv6 lookups succeed, or else point /etc/resolv.conf to a local dnsmasq with ip6.arpa set to always return NXDOMAIN. Then all IPv6 will display as the same raw IP, and you will surely notice.
Not of the git commits since 1.0pre4, but I compiled up the latest and greatest from the git repo you requested to confirm that the same bug is still there after all these years. I've attached config.h from the build.
