 Bug Type:         DOM XML related
 Operating System: Linux
 PHP Version:      4.3.3
 New Comment:

As ZendEngine1 doesn't provide capability for its extensions to track
the lifetime of the userland object that wraps an underlying libxml
object, such objects can  never be destroyed during the session
(request) at the right time.

i wonder if you could reproduce it with "while(1) 'foo';" ... there is
no free method but the last line of PHP_FUNCTION(domxml_xmltree) is
/*	xmlFreeDoc(docp); */
so that might be the problem

Yeah, I can reproduce this with: "php -r 'while(1) $i.="foo";' 
so I wouldn't call it a bug..

IIRC, there's a 'free()' method in the domxml stuff now, you should use
that.

Description:
------------
domxml_xmltree seams to have a memory leak at least with libxml 2.5.11

Reproduce code:
---------------
php -r "while(1) xmltree('<foo />');"

Actual result:
--------------
process crashes because of exceeded memory limit
