zt.c:176: REQUIRE(((zt) != ((void *)0) && ((const isc__magic_t *)(zt))->magic == ((('Z') << 24 | ('T') << 16 | ('b') << 8 | ('l'))))) failed
I started BIND (80eb7c2d) on FreeBSD 12.4-RELEASE-p1 (~/bind9/bin/named/named -c ns4/named.conf -g &), then started Flamethrower (flame --dnssec -P udp -F inet -g file -f 100k_mixed.txt -Q 1500 -p 5300 -v 99 10.53.0.4). Then I realized I wanted to do something else, so I terminated Flamethrower with Ctrl-C, then put BIND to the foreground with fg, hit Ctrl-C a bunch of times, and hit this assert:
zt.c:176: REQUIRE(((zt) != ((void *)0) && ((const isc__magic_t *)(zt))->magic == ((('Z') << 24 | ('T') << 16 | ('b') << 8 | ('l'))))) failedfull backtrace
