[boost] Does async_accept only access connection object raw pointer and wrapped it by shared pointer internally?

I don't like to use raw pointer by new and delete, but the following
code will be crashed by double delete, can't async_accept accept
shared pointer?

std::shared_ptr<session> new_session =
std::make_shared<session>(io_service_, context_);
acceptor_.async_accept(new_session->socket(),
boost::bind(&server::handle_accept, this, new_session.get(),
boost::asio::placeholders::error));

Thank you.
