Hello,

I was using nsupdate and it crashed on me:

shane@mercury:~$ nsupdate
> update delete carbon.time-travellers.nl.eu.org. 3600 IN AAAA  2a02:2770::21a:4aff:fea3:eeaa
> update delete carbon.time-travellers.nl.eu.org. 3600 IN A 46.19.37.141
> update add c..time-travellers.nl.eu.org. 3600 IN AAAA 2a02:2770::21a:4aff:fea3:eeaa
dns_name_fromtext: empty label

A typo should not cause the program to exit.
