CRT调试堆在包含exception_ptr.hpp时报告泄漏

我使用Visual Studio 2013（vc12）和Boost 1.56.0创建了一个Win32控制台应用程序。

这是我唯一的文件：

#define _CRTDBG_MAP_ALLOC
#include <stdlib.h>
#include <crtdbg.h>
//#define CHECK_THREAD
#ifdef CHECK_THREAD
#include <boost/thread.hpp>
#else
#ifdef _DEBUG
#define DEBUG_CLIENTBLOCK   new( _CLIENT_BLOCK, __FILE__, __LINE__)
#else
#define DEBUG_CLIENTBLOCK
#endif // _DEBUG
#ifdef _DEBUG
#define new DEBUG_CLIENTBLOCK
#endif
#include <boost/exception/detail/exception_ptr.hpp>
#endif
#include <Windows.h>
int main()
{
    HANDLE hLogFile = CreateFile(L"MemoryLeaks.txt", GENERIC_WRITE, FILE_SHARE_WRITE,
        NULL, CREATE_ALWAYS, FILE_ATTRIBUTE_NORMAL, NULL);
    //Turn on debugging for memory leaks. This is automatically turned off when the build is Release.
    _CrtSetDbgFlag(_CRTDBG_ALLOC_MEM_DF | _CRTDBG_LEAK_CHECK_DF);
    _CrtSetReportMode(_CRT_WARN, _CRTDBG_MODE_FILE);
    _CrtSetReportFile(_CRT_WARN, hLogFile);
    _CrtSetReportMode(_CRT_ERROR, _CRTDBG_MODE_FILE);
    _CrtSetReportFile(_CRT_ERROR, hLogFile);
    _CrtSetReportMode(_CRT_ASSERT, _CRTDBG_MODE_FILE);
    _CrtSetReportFile(_CRT_ASSERT, hLogFile);
    _CrtDumpMemoryLeaks();
    CloseHandle(hLogFile);
    return 0;
}

当我运行这个（Win32/Debug在Windows7上）时，我在MemoryLeaks.txt中得到以下输出：

Detected memory leaks!

我第一次发现这个问题是在一个包含boost/thread.hpp的单元测试中。然而，单元测试不包括有关泄漏的源代码和行信息，thread.hpp也不使用DEBUG_CLIENTBLOCK宏编译。所以我开始消除所有的include，直到我发现导致报告泄漏的是exception_ptr，幸运的是，这个包确实用宏编译了。

我开了一张票给Boost(https://svn.boost.org/trac/boost/ticket/10621)但我想我也可以在这里试试。我想我也有可能做错了什么。
