Test script:
---------------
<?php

$xmlInput = simplexml_load_string('<root></root>');
$xslInput = '<xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform"><xsl:template match="root"><xsl:text>success</xsl:text></xsl:template></xsl:stylesheet>';

$xsl = new \DomDocument();
$xsl->loadXML($xslInput);
$xslt = new \XsltProcessor();
$xslt->importStylesheet($xsl);
$xmloutput = $xslt->transformToXml($xmlInput);

echo $xmloutput;

Expected result:
----------------
Output and no crash (works fine on 5.6.13):
<?xml version="1.0"?>
success

Actual result:
--------------
On Windows:
Output:
<?xml version="1.0"?>
success

After that: 
Windows popup: "CLI has stopped working - A problem caused the program to stop working correctly. Windows will close the program and notify you if a solution is available."


On Debian:
<?xml version="1.0"?>
success
*** Error in `php': free(): invalid pointer: 0x009d994b ***
Aborted

Even after several runs, the pointer remains the same.
