http://nagoya.apache.org/bugzilla/show_bug.cgi?id=18464 Xal-C 1.5 xsl:include causes SIGSEGV on stylesheet import from Xerces 2.2 Summary: Xal-C 1.5 xsl:include causes SIGSEGV on stylesheet import from Xerces 2.2 Product: XalanC Version: 1.4.x Platform: Other OS/Version: Linux Status: NEW Severity: Major Priority: Other Component: XalanC AssignedTo: [EMAIL PROTECTED] ReportedBy: [EMAIL PROTECTED] When using Xerces to first parse an XML document and a stylesheet, and then applying the stylesheet to the XML document using Xalan, xsl:include statements. I wish to load the stylesheet via Xerces because it will be modified before being used. The problem does not occur when using either testXSLT or Xalan command-line tools also compiled from the same source files. Compiler --version: g++ (GCC) 3.2 20020903 (Red Hat Linux 8.0 3.2-7) Xerces 2.2 compiled from source, Xalan 1.5-pre from CVS (27-Mar-2003) The XercesDOMParseer is created and set to validate, and an error handler installed. Then, I call the XercesDOMParser and parse both an XML document and a stylesheet. These are sent to the function doXSLTstep() (given below) where the stylesheet can be applied to the XML document. In doXSLTstep(), the compileStylesheet() call triggers a SIGSEGV, apparently while resolving the URLs of include statements. Commenting out the include statements allows the compilation to (apparently) succeed. ------------------------ doXSLTstep() ------------------------ const DOMDocument *doXSLTstep( DOMDocument *nsDataSource, DOMDocument *tStylesheet ) { int errval; char *thisFunc = "doXSLTstep(): "; const DOMDocument *result; // create our transformer object XalanTransformer transformEngine; // this is to hold output const XalanAutoPtr<DOMDocument> theReturnDocument(DOMImplementation::getImplementation()->createDocument()); // This is a class derived from FormatterListener, which // we'll hook up to Xalan's output stage...
