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

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

PHP (and Apache) crashes after running the importstylesheet()-function
on an domdoent 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

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 domdoent();
$xsl = new domdoent();
$xsl_filecontent = file_get_contents($_SERVER["DOENT_ROOT"] .
"/evolution/gui/" . $passport->get_design("current") . "/html.xsl");
print ($processor->transformtoxml($xml));

Example 2:
It also crashes when using the example at

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.
