boost::iostream::mapped_file_impl::map_file Cannot retry mapping with hint under Windows

[ksharenkov]

Code in mapped_file.cpp

void mapped_file_impl::map_file(param_type& p)
{
    try {
        try_map_file(p);
    } catch (const std::exception&) {
        if (p.hint) {
            p.hint = 0;
            try_map_file(p);
        } else {
            throw;
        }
    }
}

As I see, function should try secondary mapping without hint if mapping with hint is failed.
Windows version has two handles ( handle_ for file and mapped_handle_ for mapping). Function cleanup_and_throw will be called If mapping failed. It will close both handles. But It is necessary to close only mapping handle for second try of mapping.
So Second try always fails under Windows if nonzero hint is passed.
*nix version has only one handle and it works.
