Hello,
Prevent crash while reloading an invalid DNS zone.
The crash happened under these circumstances:
- create a DNS zone (test.) with NS record relative to this zone (ns.test.)
- make sure that name pointed to by NS record does not have any A/ records
- restart BIND
- add missing A/ record to ns.test.
-> CRASH!
