Resolution: Fixed
Fix is in SVN; please verify
> loadGrammar is releasing a DOMBuilder previously parsed document when it
> shouldn't

>
> Key: XERCESC-1626
> URL: http://issues.apache.org/jira/browse/XERCESC-1626
> Project: Xerces-C++
> Issue Type: Bug
> Components: DOM, Validating Parser (Schema) (Xerces 1.5 or up only)
> Affects Versions: 2.7.0
> Environment: Windows XP Pro 32bit,
> Xerces-2.7.0,
> Visual C++ 6.0 sp5
> Reporter: Ori D.
>
> I'm parsing xml file using Xerces-c 2.7 DOM.
> After loading a schema grammar to the parser, my previously parsed xml
> document is released (and therefore further access to the document in the
> code causes segmentation fault)
> I do the following things (more or less):
> 1. create a XMLGrammarPoolImpl object and then create a new
> DOMBuilder using it as an input.
> m_grammarPool = new XMLGrammarPoolImpl(XMLPlatformUtils::fgMemoryManager);
> const XMLCh gLS[] = { chLatin_L, chLatin_S, chNull };
> m_DomImpl = DOMImplementationRegistry::getDOMImplementation(gLS);
> m_DomParser =
> ((DOMImplementationLS*)m_DomImpl)->createDOMBuilder(DOMImplementationLS::MODE_SYNCHRONOUS,
> 0, XMLPlatformUtils::fgMemoryManager, m_grammarPool);
> m_DomParser->setFeature(XMLUni::fgDOMNamespaces, true);
> m_DomParser->setFeature(XMLUni::fgXercesSchema, true);
> m_DomParser->setFeature(XMLUni::fgXercesSchemaFullChecking, true);
> m_DomParser->setFeature(XMLUni::fgDOMValidateIfSchema, true);
> m_DomParser->setFeature(XMLUni::fgDOMDatatypeNormalization, true);
> 2. Parse an xml file using the DOMBuilder and keep a reference to
> the DOMDocument, 'doc'
> doc = m_DomParser->parse(inputSource);
> 3. Create a new DOMInputSource and call DOMBuilder
> ->loadGrammar(inputSrc, SchemaGrammarType, true)
> SchemaGrammar *pGrammar = (SchemaGrammar*)
> m_DomParser->loadGrammar(schemaInputSource, Grammar::SchemaGrammarType, true);
> The result is that my previous parsed document, 'doc' is being released by
> the following code in parsers\DOMBuilderImpl.cpp on
> DOMBuilderImpl::loadGrammar (line 703):
> // Release DOM tree - DTD
> DOMDocument* doc = adoptDocument();
> if (doc)
> doc->release();
