Bug description: PHP crashes after serveral realods of script that uses
importstylesheet()
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.
