Memory leaks and crash with MemBufInputSource

[Nedelcho Stanev]

Hello All, I have problem using xerces 2.5.0 compiled with Visual Studio .Net on Windows 2000 Pro. I have this small source : int _tmain(int argc, TCHAR* argv[], TCHAR* envp[]) {  XMLPlatformUtils::Initialize();  int nRetCode = 0;  CString mem = "<?xml version=\"1.0\" standalone=\"no\" ?><Operation type=\"CheckID\"></Operation>"; #ifdef _DEBUG    CMemoryState oldMemState, newMemState, diffMemState;    oldMemState.Checkpoint(); #endif  MemBufInputSource memBufIS((const XMLByte*)mem.GetBuffer(), mem.GetLength(), "test", false);  XercesDOMParser *domParser  = new XercesDOMParser;  domParser->parse(memBufIS);  delete domParser;  domParser = NULL; #ifdef _DEBUG    newMemState.Checkpoint();    if( diffMemState.Difference( oldMemState, newMemState ) )    {       TRACE( "Memory leaked!\n" );    diffMemState.DumpStatistics();    } #endif  XMLPlatformUtils::Terminate();  return nRetCode; } Using CMemoryState  in this code, i see that after deleting of parser i still have memory leaks: >> Memory leaked! >> 0 bytes in 0 Free Blocks. >> 660 bytes in 31 Normal Blocks. >> 0 bytes in 0 CRT Blocks. >> 0 bytes in 0 Ignore Blocks. >> 0 bytes in 0 Client Blocks. >> Largest number used: 208270 bytes. >> Total allocations: 208270 bytes. I try lot of ways to do this parsing from buffer, but without any success, i still have this leaks and second, when i quit from program where desctructor of MemBufInputSource is executed program crash in destructor of InputSource on this place : fMemoryManager->deallocate(fEncoding); where fEncoding is NULL.I think will be better if before to try to release memory some check will be performed , like if(fEncoding)     fMemoryManager->deallocate(fEncoding); about problem with memory leak i still didn't look where is the prob, so if someone can help i will be happy :) decho
