From:             [EMAIL PROTECTED]
Operating system: RH6.2/Apache/libxml2.4.12
PHP version:      4.1.1
PHP Bug Type:     DOM XML related
Bug description:  Using unlink causes segfault

Symptoms:
- using unlink() causes segfault

Script to reproduce:

<?php
$xml = <<<END_XML
<?xml version="1.0"?>
<test>
        <foo id="x">Hello</foo>
        <foo id="y">World</foo>
</test>
END_XML;
$dom = xmldoc($xml);

// this so I can see it.
header('Content-type: text/plain');

$ctx = $dom->xpath_new_context();

$res = xpath_eval($ctx,"//foo");

foreach ($res->nodeset as $child) {
        $child->unlink();
} 

echo $dom->dumpmem();
?>

Other notes:

- some cursory debugging I did suggested that it was the cleanup routines
at the end of the script that were causing the crash.  Looking at
php_domxml.c, the recursive node memory cleanup appears to be choking on a
pointer already freed during the unlink() call.
