Hello. I use boost::asio::buffer to send a message using

void Send(const std::string& messageData)
{
    socket.async_write(boost::asio::buffer(messageData), ...);
}

And encounter "string iterator not dereferencable" runtime error somewhere
within io_service' thread. When I create objects' variable to store message
data for the buffer:

void Send(const std::string& messageData)
{
    this->tempStorage = messageData;
    socket.async_write(boost::asio::buffer(this->tempStorage), ...);
}

the error is never occured. std::string (to which messageData is referenced
to) is freed almost right after Send() calling - does boost::asio::buffer
stores just a reference to object? If so, how can I force it to store the
data by value?
