With RFC 103[45] DNS TC=1 indicated that the last section with content is incomplete and earlier sections are complete. You can have TC=1 for failure to add glue records to the additional section in a referral. *Glue records are not optional in a referral.*
With more modern DNS you need to remove the OPT/SIG(0)/TSIG records first then the examine the resulting message to find the incomplete message. If you are using OPT/SIG(0)/TSIG you are required to reserve space for those records when constructing the reply. If you are paranoid or lazy you just retry on TC=1. named is lazy in this respect.
