[Unbound-users] ldns 64-bit problem with IPv6 UDP queries?

I'm seeing a problem where drill makes UDP queries over IPv6 on 64-bit
arch to a nameserver by IP address (but not by name). amd64 and sparc64
are both affected. I'm running ldns 1.5.1 on OpenBSD.

First, what works:

drill -4 some.fqdn @ns-name
drill -4 some.fqdn @85.158.xx
drill -6 some.fqdn @ns-name
drill -6 -t some.fqdn @2a01:348:108:xx
drill -6 -t some.fqdn @2a01:348:108:xx

these respond with correct results immediately.

But, this doesn't:

drill -6 some.fqdn @ns-name
<delay, consistently 6.30s +/- 0.01s> 
error: Could not send or receive, because of network error
;; No packet received

Any ideas? Can anyone confirm whether this affects 64-bit arch
with other OS please?

Thank you.
