the following code causes Apache processes to segfault:

        echo $xsl_handle; // returns a valid xslt processor handle

        xslt_process($xslData, $xmlData, $result);
        echo xslt_error($xsl_handle);
        xslt_free($xsl_handle);

This piece of code also returns a "Warning: Supplied argument is not a valid XSLT Processor resource in *** on line 27", where line 27 is "xslt_process($xslData, $xmlData, $result); "

It obviously shouldn't crash, but the first argument to xslt_process() needs to be $xsl_handle in your case. The warning you are seeing is correct. -Rasmus

AFAIK (and according to the manual) the first argument to xslt_process() should be a string containing the XSL data ($xslData) and not the XSLT processor handle. Please advise. Then the manual is wrong. 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. Backtrace follows: Program received signal SIGSEGV, Segmentation fault. 0x40081963 in Situation::generateMessage (this=0x6f660909, type=1932358766,
