       Body:
The syntax 

            delete m_pParser, m_pParser = 0; 

seems suspicious to me; I cannot check with the C++ grammar book, but it could be the case that the Solaris compiler throws away the "delete m_pParser" part of the statement.
Try with a more standard

            delete m_pParser;
            m_pParser = 0;

       Type: Bug

   Priority: Critical

Environment: Sun Solaris Xerces 2.3

Description:
For following example Xerces does not release memory by delete m_pParser (nother by Terminate()) . It happends on Sun Solaris. Under windows it works OK.
however for i > 0 there is no allocated memory increase...

        XMLPlatformUtils::Initialize();
        for(long i = 0; i < 5; i++)
        {
            DOMNode*                    m_pRoot = 0;
	    DOMDocument*                m_pDOMDocument = 0;
	    XercesDOMParser* m_pParser = new XERCES_CPP_NAMESPACE_QUALIFIER XercesDOMParser();
            m_pParser->setDoNamespaces(true);
	    m_pParser->setValidationScheme(AbstractDOMParser::Val_Auto);
	    m_pParser->setExpandEntityReferences(false);
	    m_pParser->setIncludeIgnorableWhitespace(false);
            m_pParser->useCachedGrammarInParse(false);

             m_pParser->parse(xmlFile);
             m_pDOMDocument = m_pParser->getDocument();
             ....
             m_pRoot = m_pDOMDocument->getFirstChild();
             m_pParser->resetDocumentPool();
             m_pParser->resetCachedGrammarPool();
             delete m_pParser, m_pParser = 0;
        } 
        XMLPlatformUtils::Terminate();
