Description

There is a spurious (though apparently harmless) assert failure in XPath::findNodeSet() when compiled in Debug mode
if an expression contains an empty node-set enclosed in parenthesis, as in the following stylesheet:

<?xml version="1.0" encoding = "ISO-8859-1"?>
<xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
<xsl:template match="/">
<xsl:variable name="empty-nodeset" select="/.."/>
<xsl:variable name="foo" select="($empty-nodeset)/@bar"/>
<xsl:value-of select="count($foo)"/>
</xsl:template>
</xsl:stylesheet>

Best regards,
Alain Le Guennec.
