Here is the sample program: ... SAX2XMLReader* parser = XMLReaderFactory::createXMLReader(); XMLCh *val = XMLString::transcode("http://xml.org/sax/features/validation";); XMLCh *schema = XMLString::transcode("http://apache.org/xml/features/validation/schema";); XMLCh *full = XMLString::transcode("http://apache.org/xml/features/validation/schema-full-checking";); parser->setFeature( val, true); parser->setFeature( schema, true); parser->setFeature( full, true); parser->setExitOnFirstFatalError( true ); parser->setValidationConstraintFatal( true ); MemBufInputSource* memBufIS = new MemBufInputSource ((const XMLByte*)buf, "/path/to/asd/", false); memBufIS->setIssueFatalErrorIfNotFound( true ); WAS_XMLSAX2Handler handler("UTF-8", XMLFormatter::UnRep_CharRef, false); try { parser->setContentHandler(&handler); parser->setErrorHandler(&handler); parser->parse( *memBufIS ); errorCount = parser->getErrorCount(); } catch (const XMLException& toCatch) { cerr << "\nAn error occured\n Error: " << endl; XMLPlatformUtils::Terminate(); return 4; } The buf used in the MemBufInputSource was new'ed and read from a file.

It's either a bug with the Sun optimizer or an odd un-initialized variable in XERCES-C. I did make a change to XMLScanner.cpp and got around the crash, but I am not sure this was the right thing to do. I removed the call to fReaderMgr.reset(); on line 539 of XMLScanner.cpp. In looking at the crash stack trace, I don't like the 0x7 being passed to this function ReaderMgr::reset. I appears to me like something was already destroyed. I tried the same example on Linux with gcc 2.96 optimized with no crash.
