此代码显示了问题:

    std::cout << "stream.fail: 0         " << stream.fail() << std::endl;
    std::cout << "stream.eof:  0         " << stream.eof() << std::endl;
    std::cout << "stream.good: 1         " << stream.good() << std::endl;

    stream.exceptions(std::ios::badbit | std::ios::failbit | std::ios::eofbit);
    try{
        stream << 11;       //< Does not …
