PHP Bug Type:     DOM XML related
Bug description:  domXML causes Segfault, when you create to many Nodes

System: Apache/1.3.24 PHP running as SAPI-module (Binary from php.net)

simple script, which causes segfault 
<?
	$doc = new_xmldoc( "1.0" );
	$root = $doc->add_root("document");
	for($i = 1; $i < 1000; $i++){
		$element = $doc->create_element("element");
		$element->set_content("content ".$i);
		$root->append_child($element);
	}
	$xml = $doc->dumpmem();
	echo htmlspecialchars($xml);
?>

Description:
the content is shown shortly in the browser, but apache causes a segfault
in module php4ts.dll at offset  00096057  and finally a 404 page is
displayed.

This code causes no problems with PHP 4.1.2. When you try to create only
100 elements in this loop, it runs without any seg-faults. For complex
xmldocuments this bug makes it impossible to use domxml with php 4.2.

Modules:
php_domxml, php_xslt, php_gd und mysql
