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.

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

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.
