Thanks, I was going to ask you to file a bug report because this does
look like a bug, but I see you have already done that:
http://sourceware.org/bugzilla/show_bug.cgi?id=14307
This seems to occur only with specific host lookups (google.com and
www.gmail.com) and not others (gmail.com, google.co.in, yahoo.com,
etc). It doesn't seem related to CNAME either since the google.com
lookup does not return a CNAME.
