Warning: Call-time pass-by-reference has been deprecated - i18nsync

Warning: Call-time pass-by-reference has been deprecated - argument passed by value; If you would like to pass it by reference, modify the declaration of [runtime function name](). If you would like to enable call-time pass-by-reference, you can set allow_call_time_pass_reference to true in your INI file. However, future versions may not support this any longer. in /home/dm6/sites/all/modules/i18n/i18nsync/i18nsync.module on line 205

Changing line 205 from:
i18nsync_node_translation_attached_node(&$node, &$translation, $field);

to this:
i18nsync_node_translation_attached_node($node, $translation, $field);

has certainly helped get rid of the warning, but I was just testing modules to see what they did at this point, so I can't test to see if it works.
