http://nagoya.apache.org/bugzilla/show_bug.cgi?id=8837 Parser enters endless loop when schema processing is enabled Summary: Parser enters endless loop when schema processing is enabled Product: Xerces-C++ Version: 1.7.0 Platform: PC OS/Version: Windows NT/2K Status: NEW Severity: Normal Priority: Other Component: Validating Parser (Schema) (Xerces 1.5 or up only) AssignedTo: [EMAIL PROTECTED] ReportedBy: [EMAIL PROTECTED] If you try to parse an XML file that uses the schema below for validation the call to parse() doesn't return. If validation is turned off everything works fine. To reproduce the bug, use DOMCount or SAXCount from the parser's sample application suite and switch validation on: DOMCount.exe -v=always -n -s -f sample.xml The XML file doesn't seem to matter - the one that is attached was automatically generated by XML spy. The schema file seems to be ok, at least XML spy and SQC2.0 can't find anything to complain about. The same problem also shows up on Solaris 2.7 (parser built with gcc 2.95.3), so I don't think it's a platform or OS issue.
