使用_CrtDumpMemoryLeaks在BOOST_LOG_TRIVIAL上发生内存泄漏

Question

我正在使用visual studio 2010和boost库。我试图在主函数退出后使用_CrtDumpMemoryLeaks查找内存泄漏。我非常确定boost_log_trivial不会泄漏内存。如何避免这种误报？

源代码：

#define _CRTDBG_MAP_ALLOC
#include <boost/log/trivial.hpp>
#include <iostream>
#include <stdlib.h>
#include <crtdbg.h>

_CrtMemState initial_state;
_CrtMemState final_state;
_CrtMemState state_diff;
using namespace std;
struct AtExit
{
    ~AtExit() { 

    _CrtMemCheckpoint( &final_state );
    if ( _CrtMemDifference( &state_diff, &initial_state, &final_state) )
    {   
        _CrtMemDumpStatistics( &state_diff );
        _CrtDumpMemoryLeaks();
    }
    }
} doAtExit;

void leak_causing_fn()
{
    BOOST_LOG_TRIVIAL(error) << "Module: ";
}


int main()
{
    _CrtMemCheckpoint( &initial_state );
    leak_causing_fn();
    return 0;
}

输出：

1724 bytes in 47 Normal Blocks.
