PATCH for this bug

If the system has no IPV6 and meanwhile the DNS server is not available or no service. nslookup has segmentation fault.

How to test: set DNS server to a ip address which is not actually a DNS server.

what C library are you using ?  i wonder if this is a bug in glibc itself ... there's been a few fixed for the 2.20 release like:
