This is a long standing issue.  While rare it needs to be addressed by all vendors.  BIND sets TC=1
when it can’t fit any glue records in and if a glue record matches the qname it chooses that.  Before
anyone complains that I’ve listed a response from .GOV servers they where informed years ago about
the issue.

> Abstract:
>   The DNS uses glue records to allow iterative clients to find the
>   addresses of nameservers that live within the delegated zone.  Glue
>   records are expected to be returned as part of a referral and if they
>   cannot be fitted into the UDP response, TC=1 MUST be set to inform
>   the client that the response is incomplete and that TCP SHOULD be
>   used to retrieve the full response.

> Please note that it may take a couple of minutes from the time of submission
