dig +nssearch sometimes hangs in BIND v9.16, with an assertion failure after "ctrl+c"
This is a followup issue based on this and following comments by @leffeg in #3028 (closed) (which isn't related to the current issue).
Here are the dig -d debug messages provided by @leffeg (and copy-pasted here) for a successful run and a failed run:
