Bug Type: Bug
Bug description:Segmentation fault
Description:
------------
Using ZendFramework-1.11.10. Seg fault occurs also in 5.3.2 as well as
5.3.8. Does
not occur in 5.2.4. Difficult to reproduce, but I will include the gdb
backtrace.
Basically assigning the value of variable to another, causes the seg fault.
I can
not determine why. The line $this->_element = $element; causes the seg
fault.
Test script:
---------------
public function setElement($element)
{
if ((!$element instanceof Zend_Form_Element)
&& (!$element instanceof Zend_Form)
&& (!$element instanceof Zend_Form_DisplayGroup))
{
require_once 'Zend/Form/Decorator/Exception.php';
throw new Zend_Form_Decorator_Exception('Invalid element type
passed to decorator');
}
$this->_element = $element;
return $this;
}
Expected result:
----------------
Not this: exit signal Segmentation fault (11)
Actual result:
--------------
Program terminated with signal 11, Segmentation fault.
