MFC对话框中new创建CStatic()控件回收时出现内存泄漏

CStatic *outshow[500];
#pragma region 参数显示控件
    for(int i = 0; i < 500; i++)
    {  
        outshow[i] = new CStatic(); 
        outshow[i]->Create(_T("00000"), WS_CHILD|SS_LEFT,CRect(0,0,46,15),this,10000+i);
        //10000~~~~10499个STATIC控件
    }
回收：
void CfmudemoDlg::deleteResource()
{
for(int i = 0; i < 500; i++)
    {   delete outshow[i];  outshow[i] = NULL;  }
//delete[] outshow;

代码如上，确定执行完回收数组里全部都是0x0000000，但是每次还是会出内存泄漏不超过十个：

我想知道这是什么情况，我回收的姿势是不是有错。。。还有为什么一调delete[] outshow;就会中断呢？
求大神解答
