memory leak problem

hello,everybody:
   there is about 8K memory leak in my code below:


			try
			{
				XMLPlatformUtils::Initialize();
			}
			catch (const XMLException& toCatch)
			{
				LOG4CXX_ERROR(m_logger, "Error during initializing XML parser!(" << X(toCatch.getMessage()) << ")" );
				return;
			}
			SAX2XMLReader* parser = XMLReaderFactory::createXMLReader();
			parser->setContentHandler(this);
			parser->parse(filename);
			delete(parser);
			try
			{
				XMLPlatformUtils::Terminate();
			}
			catch (const XMLException& toCatch)
			{
				LOG4CXX_ERROR( m_logger, "Error during terminate XML parser!(" << X(toCatch.getMessage()) << ")" );
				return ;
			}

 my parser  just do nothing here, but there is about 8K memory leak.
 so i wonder whether i forget to delete something here ?

Hi,
do you still see the leak if you remove the line 
parser->setContentHandler(this)? If it disappears, you are probably 
allocating some data inside the ContentHandler callbacks.
