in-view duplicate zone not detected by named-checkconf

It doesn't seem that the configuration checker is applied effectively to zones of type 'in-view' that are declared referencing a copy of the zone that is being loaded in another view.

For example:

view "my-default" {
...

zone "yum.co.uk" IN {
	type master;
	file "yum.co.uk.zone";
};
...
};

view "another-one" {
match-clients { any; };

zone "yum.co.uk" IN {
	type master;
	file "yum.co.uk.zone";
};

zone "yum.co.uk" IN {
	in-view "my-default";
};

};

There are no errors reported when it is run through named-checkconf, but when loading, named fails when parsing the second instance of "yum.co.uk" in the second view - having not previously detected that there might be a problem loading it.

The error message reported is not particularly helpful:

02-Mar-2018 18:37:43.266 automatic empty zone: view my-default: EMPTY.AS112.ARPA
02-Mar-2018 18:37:43.266 loading configuration: already exists
02-Mar-2018 18:37:43.266 exiting (due to fatal error)

Compare this with the scenario where the same zone has been declared identically in the view:

...

view "another-one" {
match-clients { any; };

zone "yum.co.uk" IN {
        type master;
        file "yum.co.uk.zone";
};

zone "yum.co.uk" IN {
        type master;
        file "yum.co.uk.zone";
};

$ named-checkconf /etc/named.conf
/etc/named.conf:180: zone 'yum.co.uk': already exists previous definition: /etc/named.conf:175
$

Which of course is repeated if you try to start named without checking the configuration first:

02-Mar-2018 18:51:24.689 loading configuration from '/etc/named.conf'
02-Mar-2018 18:51:24.690 /etc/named.conf:180: zone 'yum.co.uk': already exists previous definition: /etc/named.conf:175
02-Mar-2018 18:51:24.690 loading configuration: failure
02-Mar-2018 18:51:24.690 exiting (due to fatal error)

It would be helpful if the in-view zones were included in the same sanity checking as other zone types, and thus generate a more helpful error message (including the line number of named.conf) for the administrator to fix.
