           Summary: busybox: nslookup: segfaults when an IPv6 nameserver
                    is listed in /etc/resolv.conf

As long as you have an IPv6 nameserver listed in /etc/resolv.conf, nslookup
will segfault.

Here's what I have observed:
* It doesn't matter if you have both IPv6 and IPv4 nameservers (if you do, the
order doesn't matter either).
* Using nslookup with only IPv4 nameserver(s) in resolv.conf seems to resolve
A, AAAA, and ip6.arpa PTR records just fine.
* The ping and traceroute applets don't seem to have a problem pinging or
tracerouting hostnames with A-only records or those with A and AAAA records.
(Of course, they only ping or traceroute via IPv4.)

I'm using Alpine Linux 2.0.0 with busybox 1.17.1 and uclibc++ 0.2.2.

Here are the corresponding APKBUILDs directly from the aports git tree:
