23032	Call get_page_hierarchy without passing by reference in wp-includes/rewrite.php page_uri_index	Askapache		"  PHP Strict Standards:  Only variables should be passed by reference in wp-includes/rewrite.php on line 825

Due to &$pages in the function declaration.
{{{
function get_page_hierarchy( &$pages, $page_id = 0 )
}}}

Instead of calling get_page_hierarchy with the full $wpdb->get_results as the arg, save the get_results to a variable and pass that to get_page_hierarchy.


{{{
$pages = $wpdb->get_results(...)
$posts = get_page_hierarchy( $pages );
}}}
