Reproducible on HEAD.
The size of the response is what seems to be causing the second query -- 6 or
more seems to be the trigger. My initial guess was that the first lookup led to
an ERANGE internally, resulting in the second query, but that should have
happened for 32-bit as well. So this might well be something else. This has
nothing to do with whether there is a CNAME in the response.
