It's not clear to me what you think the bug is. I looked at the 
www.apple.com example in your PR, the ones you listed below, and 
spot-checked a bunch of the hostnames in your freebsd.errors list. They 
fall broadly into 2 groups, either an empty CNAME chain or ANSWER=0. In 
either case, what do you think getaddrinfo()'s appropriate course of 
action should be given that there is no AAAA record to return? Please 
understand, this is not a snark, if there is a bug we want to fix it, 
but I'm genuinely confused.
