Yep, I see the same thing. Interestingly, `getaddrtest localhost.`  
(note dot) only reports one copy of ::1. (The trailing dot means  
"don't search the default DNS suffixes". A lookup for "hamster" would  
find "hamster.apple.com" on my machine here, but "hamster." would not.)

So there's definitely something fishy with getaddrinfo() here. File a  
bug report, and sanity-check the list in xauth.
