TYPO3 Core

A reference "& $this" is pass to a function on line 229 in file typo3/sysext/rtehtmlarea/pi1/class.tx_rtehtmlarea_pi1.php.

This is deprecated in PHP 5.3 and will be removed in the future.

Call this on commandline:
php -l typo3/sysext/rtehtmlarea/pi1/class.tx_rtehtmlarea_pi1.php

The only way to solve this problem in PHP 5.3 is to declare the param as a reference at the creation of the method

function bar(&$v) {
$v++;
}

Unfortunable this is not an option in this case, because the method is provided by PHP (xml_parser) itself.
