XalanC++ (Segmentation Fault)

["Victor S. Popov" <vi...@polardesign.ru>]

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";
	};
}
