Access violation when validating multiple documents against a schema

Hi,

I use the following code to validate documents (tried to distill the
relevant bits). I suspect miss some cleanup I must do on the parser
before parsing the second document.
The first document is properly parsed (when valid, otherwise errors are
reported). The second document is parsed when it is valid. If it does
not conform to the schema I get an access violation
(a pointer to an instance of ComplexTypeInfo is 0, on call to
ComplexTypeInfo::getContentModel).

Any suggestions?

main() {
...
XMLPlatformUtils::Initialize(); 
... // error handling, etc..
... // create InputSources ...
 
doc1 = parseXML(  inputXML1  );
...
doc2 = parseXML(  inputXML2  );

...
XMLPlatformUtils::Terminate(); 

}
...
DOMDocument* parseXML( InputSource& inputXML ) {
	parser = new XercesDOMParser;
	parser->setValidationScheme( AbstractDOMParser::Val_Always );
	parser->setDoNamespaces( true );
	parser->setDoSchema( true );
	parser->setExternalSchemaLocation( "MY_SCHEMA_LOCATION" );

	parser->parse( inputXML );
	
	... 
	
	DOMDocument* doc = parser->adoptDocument();
	delete parser;
	
	return doc;
}



Thx,

Andreas

Hi Andreas,
could you open a bug in Jira 
(http://issues.apache.org/jira/secure/BrowseProject.jspa?id=10510) 
attaching a compilable testcase plus all the needed XML and XSD files?

Thanks,
Alberto
