Strict warning in features_override_module_component_overrides

$code = array_pop(features_invoke($component, 'features_export_render', $module, array_keys($default), NULL));

Should be something like

$tmp = features_invoke($component, 'features_export_render', $module, array_keys($default), NULL);
$code = array_pop($tmp);

Since I'm not sure what the code does, I don't know what would be an appropriate name, which is why I'm not submitting a patch.
