[issue2007] nslookup with IPv6: assertion failed in mem.c

[Stephane Russell (via DragonFly issue tracker)]

New submission from Stephane Russell <srussell at prodigeinfo.com>:

System: DragonFly 2.8-RELEASE v2.8.2.42.g0f5d3-RELEASE i386

I enabled an IPv6 tunneling on my server. Everything went fine, except that
reverse lookups with nslookup sends a core dump. I noticed that the first run is
ok, the dumps starts on the second run.

$ nslookup ::1
Server:         127.0.0.1
Address:        127.0.0.1#53

1.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.ip6.arpa      
name = localhost.example.com.

$ nslookup ::1
