unbound dies on reboot : buffer overflow detected

[Wouter Wijngaards]

Hi Sean,

This looks like a bug that was fixed in 1.8.1, can you try with 1.8.2,
and then I'd like to be able to replicate this.  Could you tell me parts
of config pertinent to the auth-zone (because that is what seems to be
failing here)?

Best regards, Wouter
