#22774 [Com]: PHP crashes when exiting (long XML doc)

 Bug Type: DOM XML related
 Operating System: Windows 2000
 PHP Version:  4.3.2RC1
 New Comment:

Finally able to reproduce this using a simplified script:
?php
if (!extension_loaded(domxml)) @dl(php_domxml.dll);
$domR=domxml_new_doc('1.0');
$nItinerario = $domR-create_element(itinerario);
$domR-append_child($nItinerario);
?

If the extension is NOT loaded via the php.ini file, upon shutdown,
php_free_xml_doc is called first and then php_free_xml_node for the
created element is called which causes the blow up. If read from the
ini file, php_free_xml_node is called first and then php_free_xml_doc.

Seems to be some issue with the external loading of the extension.

Am not able to reproduce in Win 2K. Ran it for 10,000 and 20,000
iterations without a problem. Finally ran it for 1,000,000 iterations
until the machine ran out of memory (was over a Gig of used memory at
that point).
Once getting a fatal emalloc error memory returned back to normal
(exact amount used prior to running).

Tested against latest cvs code as well as a php4-3.0-dev build from jun
2002.

using libxml2-2.4.22

looks like a mem-leak

linux normally doesn't segfault on memleaks. Windows does... that's the
difference ;)

I try to look at it

If you see DrWatson output there is the function zend_timeout 

I don't know if that matchs something.

I've updated to 4.3.2-RC1 version, and updated php4ts.dll on
winnt/system
Same bug.

Please try using this CVS snapshot:

For Windows:
 
  http://snaps.php.net/win32/php4-win32-STABLE-latest.zip

And make sure you really update it. Especially the php4ts.dll file.
