PHP version: 5.2.0
PHP Bug Type: SimpleXML related
Bug description: Massive memory leak
Description:
------------
The combination of simplexml and htmlspecialchars() creates massive memory
leak. In a about 500k calls to htmlspecialchars() on a value in simplexml,
it eats up over 1GB of memory.
Reproduce code:
---------------
$xml = simplexml_load_file('some_xml_file.xml');
$val = '';
for ($index=0; $index<10000000; $index++)
{
$val = htmlspecialchars($xml->title);
}
Expected result:
----------------
If you run the above script and watch Windows Task Manager, you will see
memory usage continuous to go up non-stop.
