Current code from 2.6.1
======================================================
if ( $cache = wp_cache_get( 'get_pages', 'posts' ) )
if ( isset( $cache[ $key ] ) )
return apply_filters('get_pages', $cache[ $key ], $r );
======================================================
Proposed code
======================================================
if ( $cache = wp_cache_get( 'get_pages', 'posts' ) )
if ( isset( $cache[ $key ] ) )
{
$retval = apply_filters('get_pages', $cache[ $key ], $r );
return $retval;
}
