So the server is definitely serving hosts (ypcat hosts lists many local ips). 
Without the nis or with nis after dns in the hosts line everything works fine.

Here are a couple straces of "curl google.com":
With nis in hosts line (seg fault):

Without nis in hosts line:
http://www.cs.man.ac.uk/~brejc8/temp/nis_curl2.trace

It would be great if someone else tried this so I can work out if it is our 
servers or a general issue.

On the nis topic, I spent ages this afternoon trying to figure out why 
package-manager would not allow me to install anything. Eventually I found the 
cause was the nis groups overriding the file ones and polkituser group number 
was being used (sigh, Why oh why do admins keep using sub 500 group numbers?).
