New data :

* 2.2STABLE4 on linux 2/0/36 :
----------------------------
#./dnsserver
server01
$addr 0 3.3.3.3

so it works

* 2.2STABLE5 on same machine
----------------------------
# ./dnsserver
server01
$fail DNS Domain 'server01' is invalid: Host not found (authoritative).

doesn't work, but:

#./dnsserver -D
server01
$addr 0 3.3.3.3

So it seems that that something change ...
