Created Feb 07, 2020 by Michal Nowak@mnowakOwner

named assertion failed in interfacemgr.c on FreeBSD 12.1

(This might be a similar issue as #1604 (closed), but with a different backtrace and that I can't reproduce it.)

I have a FreeBSD 12.1 under KVM (6 vCPU, 8 G RAM), where I triggered a core dump of named by running system test under a tight loop (e.g. while true; do make -j6 -k test V=1; done) and pressed Ctrl-C.

Here's the backtrace:

Core was generated by `/usr/home/newman/bind9/bin/named/.libs/named -D addzone-ns2 -X named.lock -m rec'.
Program terminated with signal SIGABRT, Aborted.

Backtrace stopped: Cannot access memory at address 0x7fffdf1f7000

A more detailed backtrace follows, but the core file and the named binary are gone: core.gdb.
