The code is clearly expecting arguments in this order: resource processor, string xml, string xsl -Rasmus I adapted the php source to read xslt_process($xsl_handle, $xmlData, $xslData);, and this results in another (weird) segfault.

Please advise. Then the manual is wrong. The code is clearly expecting arguments in this order: ext/sablot or ext/xslt ? The manual seems to be right for old ext/sablot.
