[TYPO3-commerce] Call-time pass-by-reference has been deprecated

[Martin Alker]

Hello,

I get this message in the frontend on the checkout page:

Warning: Call-time pass-by-reference has been deprecated; 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. in 
/home/xyz/public_html/xyz/htdocs/typo3conf/ext/commerce/pi3/class.tx_commerce_pi3.php 
on line 459

I use TYPO3 4.1.1, PHP 5, commerce 0.9.2, dynaflex 1.9.0

What's the problem?
