Description: ------------ Using registerPHPFunctions and calling a PHP function from XSL with first parameter an XSL Variable (instead of node, node-text, etc.) produces a memory leak. Also "memory_limit" directive in php.ini is ignored. Reproduce code: --------------- <?php // XML Contents $sXML = <<< EOD <?xml version="1.0" encoding="UTF-8"?> <root>root node</root> EOD; $domXML = new DOMDocument(); $domXML->loadXML($sXML); // XSL Contents $sXSL = <<< EOD <xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform" xmlns:php="http://php.net/xsl"> <xsl:template match="/"> <xsl:variable name="variable"> text </xsl:variable> <xsl:value-of select="php:functionString('trim', \$variable)" /> </xsl:template> </xsl:stylesheet> EOD; $domXSL = new DOMDocument(); $domXSL->loadXML($sXSL); // XSLT Processor $xsltProcessor = new XSLTProcessor(); $xsltProcessor->registerPHPFunctions(); $xsltProcessor->importStyleSheet($domXSL); while (true) { $xsltProcessor->transformToDoc($domXML); } Expected result: ---------------- Nothing. Actual result: -------------- All server available memory is used. -- Edit bug report at http://bugs.php.net/?id=44891&edit=1 -- Try a CVS snapshot (PHP 5.2): http://bugs.php.net/fix.php?id=44891&r=trysnapshot52 Try a CVS snapshot (PHP 5.3): http://bugs.php.net/fix.php?id=44891&r=trysnapshot53 Try a CVS snapshot (PHP 6.0): http://bugs.php.net/fix.php?id=44891&r=trysnapshot60 Fixed in CVS: http://bugs.php.net/fix.php?id=44891&r=fixedcvs Fixed in release: http://bugs.php.net/fix.php?id=44891&r=alreadyfixed Need backtrace: http://bugs.php.net/fix.php?id=44891&r=needtrace Need Reproduce Script: http://bugs.php.net/fix.php?id=44891&r=needscript Try newer version: http://bugs.php.net/fix.php?id=44891&r=oldversion Not developer issue: http://bugs.php.net/fix.php?id=44891&r=support Expected behavior: http://bugs.php.net/fix.php?id=44891&r=notwrong Not enough info: http://bugs.php.net/fix.php?id=44891&r=notenoughinfo Submitted twice: http://bugs.php.net/fix.php?id=44891&r=submittedtwice register_globals: http://bugs.php.net/fix.php?id=44891&r=globals PHP 4 support discontinued: http://bugs.php.net/fix.php?id=44891&r=php4 Daylight Savings: http://bugs.php.net/fix.php?id=44891&r=dst IIS Stability: http://bugs.php.net/fix.php?id=44891&r=isapi Install GNU Sed: http://bugs.php.net/fix.php?id=44891&r=gnused Floating point limitations: http://bugs.php.net/fix.php?id=44891&r=float No Zend Extensions: http://bugs.php.net/fix.php?id=44891&r=nozend MySQL Configuration Error: http://bugs.php.net/fix.php?id=44891&r=mysqlcfg
