PHP Bug Type: Reproducible crash
Bug description: list($a, $b) = $var = function() seg faults
Description:
------------
When testing our site in PHP5 I can across a repeatable segmentation fault
whenever the HTML_QuickForm_Controller::run() function was called. The
problem was tracked to line 131 of Controller.php in
HTML_QuickForm_Controller 1.0.2. The problem occured in both PHP-5.0.0-RC1
and the php5-200404041830 snapshot. I have unfortunatly been unable to
create a simpler test case that causes the problem however it is readily
repeatable in HTML_QuickForm_Controller.
Reproduce code:
---------------
Problem Line 131:
list($page, $action) = $this->_actionName = $this->getActionName();
Changing the line to this prevents this problem from occuring.
$this->_actionName = $this->getActionName();
list($page, $action) = $this->_actionName;
Expected result:
----------------
$page and $action are set to the first and second items in the array
respectivly
Actual result:
--------------
segmentation fault.
