Bug description:storing SimpleXMLObject to class property does not always work
(is null)
Description:
------------
The PHP-Version is 5.3.3-7 (was not able to select this version in the
dropdown box)
When storing a SimpleXMLObject to a class property the property is null
sometimes (every 3rd - 5th call).
According to this error, PHP seems to loose all object descriptors ($this)
in *all* classes, which leads to misleading error messages like "trying to
get property of non-object in ..", even if I checked $this to be an object
1 line before the error message happens (How can $this be not an object? I
am always in object context).
Current solution: When casting the SimpleXMLObject to an Array and storing
it to the class property both problems do not appear.
Test script:
---------------
class ProjectXML {
private $project_xml;
public function foo((SimpleXMLObject) $xml, $search_criteria) {
// search a specific node, save it to the class property and return
true
$this->project_xml = $xml_node;
return true;
}
public function bar() {
var_dump($this->project_xml);
}
}
$class = new ProjectXML();
$class->foo(simplexml_load_file("/path/to/project.xml"));
$class->bar();
/*
The used code is very complex, so I reduced it to a minimum. The full code
can be viewed here:

*/
Expected result:
----------------
SimpleXMLObject
Actual result:
--------------
sometimes null
sometimes the SimpleXMLObject
