Asynchronous 无边界的\u缓冲区、\u CRTSETDBGSFLAG和内存泄漏

我正在尝试使用其中一个新特性—异步代理库。我刚刚加了一个

无界缓冲区m_myDataBuffer； 到我的C++类，没有更多-没有代理运行。 要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

但在关闭我的应用程序窗口（我使用的是简单的Win 32 GUI应用程序）后，Visual Studio显示了大量内存泄漏：

Detected memory leaks!

无边界缓冲区有什么特别之处吗？我必须做些什么才能释放它，即使它没有被使用？或者我需要以某种特殊的方式设置_crtsetdbglag？_crtsetdbgsflag是内存泄漏的原因，还是在这种情况下，它以某种方式创建了错误检测，并且没有真正的内存泄漏？我错过了什么

我100%确信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__)

\ifdef\u调试
#定义\u CRTDBG\u映射\u ALLOC
#包括
#包括
#定义新的（正常块、文件、线）

---

在我的stdafx.h中，代码中的内存泄漏有文件名和行。但是无界缓冲区的那些没有这样的信息，所以我猜这意味着它们来自代理库。

好的，我发现“CRTDBG\u LEAK\u CHECK\u DF flag”会自动调用“CrtDumpMemoryLeaks（）；在申请结束时。但这似乎不是在最后发生的。我删除了_CRTDBG_LEAK_CHECK_DF并在main（）的末尾调用了_crtdumpmomeryleaks（），现在它正确地报告了内存泄漏。。。我希望如此

微软MSDN中也有关于PPL库内存泄漏的错误报告，希望他们能尽快修复

_CrtSetDbgFlag ( _CRTDBG_ALLOC_MEM_DF | _CRTDBG_LEAK_CHECK_DF );

#ifdef _DEBUG
#define _CRTDBG_MAP_ALLOC
#include <stdlib.h>
#include <crtdbg.h>
#define new new(_NORMAL_BLOCK,__FILE__, __LINE__)
