Description:
------------
Calling domDocument::load() from within a class method PHP crashes.
Reproduce code:
---------------
<?php
class docLoader {
public function __construct($xslFile) {
$xsltDoc = domDocument::load($xslFile);
}
}
$doc = new docLoader('file.xsl'); // does not work
// however
$xsltDoc = domDocument::load('file.xsl'); // still works
?>
Expected result:
----------------
Should return object
Actual result:
--------------
Both PHP CLI and Apache module crash. Only when domDocument::load() is called from a class method.
