ASIO has nothing to do with it. You wrap your function with
packaged_task, and it doesn't propagate exceptions.

Modify your example as follows to see what happens:

struct task
{
//....
    void operator()()
    {
      (*pt_)();
      boost::unique_future<void> fi=pt_->get_future();
      assert(fi.has_exception());
    }
//...
};
