Stream contains the XML-content. But the segmentation fault seems to be caused when the error handler tries to access null pointer (probably filename).

If you're using a stream, it should hold the contents of your XML files. Otherwise, just use something like: XSLTInputSource xmlIn("foo.xml"); XSLTInputSource xslIn("foo.xsl"); XSLTResultTarget xmlOut("foo-out.xml"); Regards, -Charles -----Original Message----- From: Victor S.

Same pattern (core dumped) with stringstreams.

It's in <sstream>. We had all sorts of memory leaks and crashes using strstreams that went away when we migrated to stringstreams. HTH -chas -----Original Message----- From: Victor S. Popov [mailto:[EMAIL PROTECTED] Sent: Tuesday, January 22, 2002 11:54 AM To: [email protected] Subject: XalanC++ (Segmentation Fault) Hi! We are trying to use XalanC++ to transform XML to HTML. I've tried to use string streams as input sources and got "Segmentation Fault" in case of invalid XSL-source by the means of structure, i.e. no exception was thrown. Nevertheless when I use files with the same sources (invalid XSL) instead of streams, it works - transformer treats the error normally. Here is the code of prototype: XML: <?xml version="1.0"?> <document attribute="Test"/> XSL: <?xml version="1.0"?> <xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform";> <xsl:value-of select="."/> <!-- structural trap --> <xsl:template match="/"> <html><body>Test</body></html> </xsl:template> </xsl:stylesheet> CODE: { istrstream xml_stream (xml_text, strlen (xml_text)); istrstream xsl_stream (xsl_text, strlen (xsl_text)); XalanTransformer xalan; XSLTInputSource xml (& xml_stream /* "xml.xml" */); XSLTInputSource xsl (& xsl_stream /* "xsl.xsl" */); XSLTResultTarget output (cout); try { if (xalan.transform(xml, xsl, output) != 0) cout << xalan.getLastError () << endl; } catch (...) { cout << "ERROR"; }; } BT: Program terminated with signal 11, Segmentation fault.
