I run src-built nginx/1.3.2 on linux/64.

I have two nginx vhosts enabled:
site 1)
...
server {
server_name test1.loc;
listen 10.0.0.1:443;
listen [2001:xxx:xxxx:xxx::1]:443 ipv6only=on;
...

site 2)
...
server {
server_name test2.loc;
listen 10.0.0.1:443 default;
# listen [2001:xxx:xxxx:xxx::1]:443 ipv6only=on;
...[code]

With this config, if I start nginx,

service nginx start
Shutting down nginx done
Starting nginx done

all's well.

But, if for site 2) I enable the IPv6 listener,

- # listen [2001:xxx:xxxx:xxx::1]:443 ipv6only=on;
+ listen [2001:xxx:xxxx:xxx::1]:443 ipv6only=on;


Now, @ nginx start,

service nginx start
Starting nginx nginx: [emerg] duplicate listen options for [2001:xxx:xxxx:xxx::1]:443 in /usr/local/etc/nginx/sites-enabled/test2.loc.conf:21
startproc: exit status of parent of /usr/local/sbin/nginx: 1
failed


Is this a bug, feature or config problem?

Thanks.
