Problems with Samples for Xerces2.3

[Rebecca Vernon]

Hi,   Thanks for looking at this post. I've recently downloaded Xerces2.3 C++ and have managed to compile and build the Bcc.551 code (using the patch provided for bug 20353). However, I cannot get the sample programs to successfully run. Whenever a new SAX or DOM parser is created I get an access violation in the constructors of either XMLBufferMgr.cpp or XMLBuffer.hpp (see code at bottom of post). The exceptions thrown include "Read of Address: xxx", where xxx is the adress of the MemoryManager passed in to the constructor.   Has anybody else experienced these problems or got any ideas about what I might be doing wrong? Any help would be gratefully received.   Thanks, Rebecca Vernon Research Scientist - QinetiQ     ************************************************************************ XMLBufferMgr::XMLBufferMgr(MemoryManager* const manager) :     fBufCount(32)     , fMemoryManager(manager)     , fBufList(0) {     // Allocate the buffer list and zero it out     // *** VIOLATION THROWN ON LINE BELOW ***     fBufList = (XMLBuffer**) fMemoryManager->allocate(fBufCount * sizeof(XMLBuffer*)); // new XMLBuffer*[fBufCount];     for (unsigned int index = 0; index < fBufCount; index++)         fBufList[index] = 0; }   ************************************************************************ XMLBuffer(int capacity = 1023               , MemoryManager* const manager = XMLPlatformUtils::fgMemoryManager) :           fUsed(false)         , fIndex(0)         , fCapacity(capacity)         , fMemoryManager(manager)         , fBuffer(0)     {         // Buffer is one larger than capacity, to allow for zero term        // *** VIOLATION THROWN ON LINE BELOW ***         fBuffer = (XMLCh*) manager->allocate((capacity+1) * sizeof(XMLCh)); // new XMLCh[fCapacity+1];           // Keep it null terminated         fBuffer[0] = XMLCh(0);     } *********************************************************************************
