This will be tricky.  The user has been testing with bind9 from Jammy,
and reported the problem against the Focal package.

I agree with Paride's last comment where he says:

  OTOH if it does *not* crash, then we can consider bisecting and
  finding out which new version fixed the issue, and then dig even
  deeper and try finding out which commit or commits make the
  difference. That won't be an easy task, especially given that the
  reproducibility of this crash is low. I don't think we're going to do
  this unless an easier way to trigger the crash is found.

Given that the bug sometimes takes a long time to manifest (1 month), if
we were to bisect this we could be looking at spending a very long time
to find something.

I will leave a comment in the bug explaining what I said above and
trying to provide some alternative approaches to the user.
