The typemap automatically creates a reference to it and returns the reference. It's refcount is off by one, though. 

use strict;
use warnings;

use Devel::Peek qw( Dump );

use Inline C => <<'__EOI__';

AV* f() {
   return newAV();
}

__EOI__

Dump(f());

Making it mortal doesn't help. So unless I'm missing something, this can only be used if you actually hold a reference to the array you return.
