Description:
------------
PHP (and Apache) crashes after running the importstylesheet()-function on an domdocument serveral times (means serveral reloads of the same script, not use of this function serveral times in the same script).

If the XSL-input is large (> 50kb) PHP crashes after 3-5 site reloads. If the XSL-input is small it seems that PHP crashes after 10-20 site reloads. The very strange thing is that it renders the page with the *same* XSL/XML-input serveral times  without problems before crashing after a certain amount of realods. It seems not to be important what XSL-ruleset is used. I tested serveral xsl-inputs and it always died.

It crashes just on Windows (Apache and Apache 2). I used the libxml that came with PHP as well as the latest from xmlsoft.org.

There are no problems under Linux. 
 

Reproduce code:
---------------
Example 1:
$output is the XML-string (sorry this is very long so I can't post it, but the xml-string is not import to reproduce to error, as well as the XSL-string isn't)

$processor = new xsltprocessor();
$xml = new domdocument();
$xsl = new domdocument();
$xsl_filecontent = file_get_contents($_SERVER["DOCUMENT_ROOT"] . "/evolution/gui/" . $passport->get_design("current") . "/html.xsl");
$xsl->loadxml($xsl_filecontent); 
$xml->loadxml($output);
$processor->importstylesheet($xsl);
print ($processor->transformtoxml($xml));

Example 2:
It also crashes when using the example at 
http://news.php.net/article.php?group=php.xml.dev&article=148



Expected result:
----------------
transformed xml output

Actual result:
--------------
Sorry I can't give you a backtrace with my windows-system. I can just tell you that the last call goes to libxml2.dll.

Please note that the 2nd example still includes the old functionnames (which worked with beta1). I certainly changed them to work with snapsshots.

This issue still applies and also for transformtodoc in Beta 1 through the build of CVS WIN32 Built On: Aug 07, 2003 10:30 GMT.

Same random crashes when the two functions are called on the same page repeatedly. Sometimes after 2 reloads, sometimes 10. It also appears to depend on the size of the XSL file, the XML file does not seem to matter.
