I spent some time investigating this issue today and found a possible fix in an upstream Merge Request:

https://gitlab.isc.org/isc-projects/bind9/-/merge_requests/3721

I'm not entirely confident that this is the same issue because the MR talks about a crash that happens on isc__nm_tcpdns_send, while the coredump provided by John crashes on isc__nm_tcp_send. Either way, I went ahead and backported the patch to the current version of bind9 on Focal. You can find builds of the new package in the following PPA:

John et al: since you haven't provided instructions on how to reproduce the bug yet, would you be able to give the PPA above a try and report back with results, please?

Thank you in advance.
