Bug #16888 Updated: domXML causes Segfault, when you create to many Nodes

ID: 16888 Updated by: chregu@php.net Reported By: cb@designassembly.de Status: Feedback Bug Type: DOM XML related Operating System: Windows XP PHP Version: 4.2.0 New Comment: Edin created a new php_domxml.dll with libxml2-2.4.21 compile d in. It's available at http://ftp.proventum.net/pub/php/win32/php_domxml.zip Can you check that. But i fear, it doesn't help solve the problem :( Please be aware, that append_child changed the meaning in 4.2.1. The former append_child is now append_sibling, and append_child behaves like the w3c likes it. But appending a sibling to the root node, doesn't make really sense, but it souldn't crash PHP, either :) I would be very glad, if someone with windows programming experience could hunt down the problem. chregu Previous Comments: ------------------------------------------------------------------------ [2002-05-15 17:50:13] jtate@php.net FWIW, the sample script works ok using the latest HEAD under IIS in debug mode...well, works is an approximation. It doesn't crash until the Zend tries to clean up memory, and then crashes in _zval_ptr_dtor. Not feeling like a Zend guru today, I don't feel like attacking it. I'll try Apache though to see if I can narrow this bug down. ------------------------------------------------------------------------ [2002-05-15 16:15:27] cb@designassembly.de I tried the newest xml-lib build from http://www.fh-frankfurt.de/~igor/projects/libxml/ (Version 2.4.21) and apache still crashes. I also can confirm the barrier with 128 elements. ------------------------------------------------------------------------ [2002-05-15 12:28:24] flying@dom.natm.ru One more interesting remark - DOM XML module crashes if more then 128 elements are created. Less then 128 elements are created without problems. Maybe it will help you somehow? ------------------------------------------------------------------------ [2002-05-15 12:23:10] flying@dom.natm.ru Confirmed under windows 2000 server running as CGI with following combinations: PHP 4.1.1 + libxml2 2.4.21 - works well PHP 4.2.0 + libxml2 2.4.21 - crash PHP 4.2.1 + libxml2 2.4.9 - crash Unfortunatelly latest PHP version - 4.2.1 have been build with libxml2 compiled as static library, so i can't test it with latest libxml2. So it is not a problem of libxml2, but something into DOM XML module itself. PHP crashes into final stage, when script execution itself is completed (and even function, registered as shutdown function have been executed). ------------------------------------------------------------------------ [2002-05-15 08:57:08] chregu@php.net I would blame libxml2 :) Do you have the latest libxml2 dll? (available anywhere from http://www.xmlsoft.org). Can you check with that? chregu ------------------------------------------------------------------------ The remainder of the comments for this report are too long.
