Hi Will, thanks for your quick answer.

True. Here is the updated code:

#define _CRTDBG_MAP_ALLOC

#include <stdlib.h>
#include <crtdbg.h>

#define BOOST_FILESYSTEM_VERSION 3
#include <boost/filesystem/convenience.hpp>

namespace fs = boost::filesystem;

int main(int argc, char* argv[])
{
    {
        fs::path my_path( "C:/bla.dat" );
    }

    _CrtDumpMemoryLeaks();

        return 0;
}

-- output:

It's getting late here. Maybe I don't see the forest because there are tree? ;-)
