我正在尝试使用其中一项新功能 - 异步代理库。我刚刚添加了一个
unbounded_buffer m_myDataBuffer; 到我的 C++ 类，仅此而已 - 还没有代理运行。
为了在我的应用程序中启用内存泄漏检测，我使用：
#ifdef _DEBUG
_CrtSetDbgFlag ( _CRTDBG_ALLOC_MEM_DF | _CRTDBG_LEAK_CHECK_DF );
#endif
但是在关闭我的应用程序窗口后（我使用的是简单的 Win 32 GUI 应用程序）Visual Studio 显示了一堆内存泄漏：
Detected memory leaks!

Object dump complete.
在我注释掉之后泄漏就消失了
unbounded_buffer<int> m_myDataBuffer;
或者在我注释掉之后
_CrtSetDbgFlag ( _CRTDBG_ALLOC_MEM_DF | _CRTDBG_LEAK_CHECK_DF );
unbounded_buffer 有什么特别之处吗？即使不使用，我也必须释放它？还是我需要以某种特殊方式设置 _CrtSetDbgFlag？_CrtSetDbgFlag 是内存泄漏的原因，还是在这种情况下以某种方式创建错误检测并且没有真正的内存泄漏？我在这里想念什么？
我 100% 确定这些泄漏不是来自我的代码，因为我也有
#ifdef _DEBUG
#define _CRTDBG_MAP_ALLOC
#include <stdlib.h>
#include <crtdbg.h>
#define new new(_NORMAL_BLOCK,__FILE__, __LINE__)
在我的 stdafx.h 中，所以我的代码中的内存泄漏具有文件名和行。但是那些 unbounded_buffer 没有这样的信息，所以我猜这意味着它们来自代理库。
