Hi,

I am getting two empty strings from the following program,

void boost_split_test() {

    const string &text("-");

    vector<string> tokens;

    split(tokens, text, boost::is_any_of("-"), token_compress_on);

    cout << "size of tokens " << tokens.size() << '\n';

    for (auto const &e : tokens)

        cout << e.size() << '\n';

}

Output:

size of tokens 2
0
0

Is this expected output? I expecting an zero split parts. Could someone
clarify?
