Please submit a new report. This is totally useless/confusing.
You should fill all the textboxes in the "report a bug" page..

Hello,

This problem lies in the fact that the variable $x = array(0 => 1) after passing 
through the function x() changes its value on the array(0 => 0), if prior to 
entering the function do:
$aaa = &$x[0];

Regards.
