OK, so I setup a VM and installed Centos 7 on it, installed the packages 
as per the wiki and compiled 4.4.0. I then found I didn't have 
pam_winbind.so
Compared what the wiki said to install for Centos with what I normally 
install for Devuan and installed the difference, recompiled again, I now 
had pam_winbind.so

Set up Samba and joined it to the domain and everything works until you 
add the word 'wins' to the hosts line in /etc/nsswitch.conf.

I now get this:

ping -c1 google.com
Segmentation fault

I have disabled selinux, turned off the firewall, it doesn't matter if 
the Samba Deamons are running or not.

All I can find that might be relevant is this:

I cannot get valgrind or gdb to give any result, they both fail.

I am becoming more convinced that this has nothing to do with Samba and 
as I normally don't use Centos, I am giving up.
