Incorrect visitor parsing

[alex3d]

It seems that parser interface broken when stream contains more than one object and contains strings.
Strange behavior can be verified with slightly modified example/cpp11/socket_stream_example.cpp:

    std::string vvi1 = "a";
    std::string vvi2 = "bcdef";
    //std::map<std::string,std::string> vvi1 { {"a","b"}  };
    //std::map<std::string,std::string> vvi2 { {"c","d"}  };
``

Expected output:
"a"
"bcdef"

Output:
"a"
"�"
"b"
"c"
"d"
"e"
"f"
