Description:
------------
This code in HTML_QuickForm::addElement() line 594 (version 3.4pl1) :

$this->_elements[] =& $elementObject;
$this->_elementIndex[$elementName] = end(array_keys($this->_elements));

where $elementObject is an HTML_QuickForm_element object returns a Fatal error :

Fatal error: Only variables can be passed by reference in /usr/lib/php/HTML/QuickForm.php on line 594

It worked fine with Php 5.0.4

Thank you for taking the time to write to us, but this is not
a bug. Please double-check the documentation available at
http://www.php.net/manual/ and the instructions on how to report
a bug at http://bugs.php.net/how-to-report.php

Actually, never mind - this is bogus. 

http://no2.php.net/end lists:

mixed end ( array &array )

a return value is not a variable, and thus can not be passed by reference.
