// We are using boost 1_67_0

// We have this code:
auto channel = boost::make_shared<Channel>(host, port, user, pass, vhost, 131072);

// And it crashes at run-time in make_shared. The crash occurs here:

template< class T, class... Args > typename boost::detail::sp_if_not_array< T >::type make_shared( Args && ... args )
{
    boost::shared_ptr< T > pt( static_cast< T* >( 0 ), BOOST_SP_MSD( T ) );
    boost::detail::sp_ms_deleter< T > * pd = static_cast<boost::detail::sp_ms_deleter< T > *>( pt._internal_get_untyped_deleter() );
    void * pv = pd->address();
    ::new( pv ) T( boost::detail::sp_forward<Args>( args )... );
    pd->set_initialized(); //   <---------------------------------- HERE
    T * pt2 = static_cast< T* >( pv );
    boost::detail::sp_enable_shared_from_this( &pt, pt2, pt2 );
    return boost::shared_ptr< T >( pt, pt2 );
}

//The declaration of Channel can be found here:

// We also tried making our own dummy struct to se if we could reproduce the crash, but it runs fine:
    struct lolbob {
        std::string host;
        int port;
        std::string user;
        std::string pass;
        std::string vhost;

        explicit lolbob(const std::string &host,int port, const std::string &user, const std::string &pass, const std::string &vhost)
            : host(host)
            , port(port)
            , user(user)
            , pass(pass)
            , vhost(vhost)
        {
            std::cout << "lolbob ctor host=" << host << ", user=" << user << ", pass=" << pass << ", virtualhost=" << vhost << endl;
        }
    };

    auto bahn=boost::make_shared<lolbob>(host, port, user, pass, vhost );
