内存崩溃的BUG 之 另一case 2

内存崩溃的BUG 之 另一case 1

查了一下，原来是引用计数里面的  m_count++,  用得有问题！

#include <iostream>
using namespace std;

#include <windows.h>
#include <process.h>

DWORD g_value = 0;
#define NUMBER_COUNT 2000

void __cdecl threadfun(void* pVoid)
{
 for (int i = 0; i <= NUMBER_COUNT; i++ )
 {
  // g_value++;
  // g_value--;

  InterlockedIncrement((long*)&g_value);
     InterlockedDecrement((long*)&g_value);
 }
}

int main()
{
 int i = 0;

 g_value = 1;

 HANDLE hArray[NUMBER_COUNT] = {INVALID_HANDLE_VALUE};
 for ( i = 0; i <= NUMBER_COUNT; i++ )
 {
  hArray[i] = (HANDLE)_beginthread(threadfun, 0, (void*)i);
 }

 for ( i = 0; i <= NUMBER_COUNT; i++ )
 {
  DWORD dwRet = 0;
        DWORD dwExitCode = 0;
        if( TRUE == ::GetExitCodeThread(hArray[i], &dwExitCode) )
        {
            if( STILL_ACTIVE == dwExitCode )           
                dwRet = ::WaitForSingleObject(hArray[i], INFINITE); // INFINITE
        }
 }

 cout << g_value << endl;

 return 0;
}
