Package: pdns-server
Version: 2.9.21.1.0-1
Severity: important

Hi there,

I am using pdns with the bind backend and am experiencing trouble with
AAAA records since the upgrade from Etch to Lenny.  Interestingly only
on records on the toplevel of the zonefile (in my case 2nd level
domains).  It seems that there is some memory corruption going on.
The addresses are different whenever I reload pdns and I think that they
also vary when they got pulled from the cache.

The server in question is publically reachable.

Some snippets from the zonefile:
[...]
@       IN A    88.198.49.206 ; durotan
@       IN AAAA 2001:6f8:900:17a::2 ; durotan
[...]
durotan.ipv6    IN AAAA 2001:6f8:900:17a::2
[...]

The A query works just fine.  Normal zone entries work, too:
