note 13472 deleted from function.preg-replace-callback by sniper

Note Submitter: franco@netwheel.com ---- First, sorry for my elementary english. On my box the preg_replace_callback( "/(\w+)/", array( $this, callback_method ), $string) seems to works properly but, after the execution the object seems to have lost the datas added from the callback method. Everyting works well if the $this parameter is passed to callback method as reference like preg_replace_callback( "/(\w+)/", array( &$this, callback_method ), $string) Also I noted that the compiler take the reference without any warning message regards 'Call-time pass-by-references deprecated'. Ciao.
