Strange issue in combination with qname-minimsation

Unbound
1

Hi,

Here is my situation:

Unbound: 1.7.1
qname: euc-word-edit.officeapps.live.com
Listening on IPv4 + IPv6

Steps:

- Reload Unbound
- Query for $qname on the IPv4 address (good reply)
- Queray again for $qname on the IPv6 address (servfail)

If I disable qname-minimisation it works, there are no servfails.

It doesn't matter if I start with the IPv4 address of the IPv6 address, but once it has succesfully resolved over the one, it won't resolver over the other.

Can you reproduce?

Bug or feature?

UPDATE:

Problem seems gone with Unbound 1.7.3 - sorry for bothering.
