Bind 8.2.3, zone rejected due to CNAME error

[Peter.Pedersen at sas.dk]

Hi,

The version 8.2.3 of bind reject the entire zone, when it find an error in a
CNAME e.g.

server.foo.com.	IN A 172.1.1.200
server.foo.com.	IN CNAME host.foo.com.

The behaviour seems to be the same for both "check-names warn/ignore"
options, and the server does not answer any queries for this zone and does
not allow any zone-transfer.
 
The previous version 8.2.2 pl 5 did also reject the zone, but the result was
different, it continued to answer queries for the zone, but did not allow a
zone-transfer.

Are the "No answer to queries" inteded, or is it a bug/feature?
How can we avoid it?

We are running some unattended updates to the zone-files, which can cause in
CNAME-errors, and would prefer the "old" behaviour, since it only affected
the zone-transfer and not the queries.

Thanks in advance
