BTW, I've noticed that if I call boost::future::get() twice in my continuation, on the same future object, the second call throws, saying:
Operation not permitted on an object without an associated state
you can find the example at:

Am I missing something? Looking at both std::future and boost::future documentation, I see no indication that calling get clears the state.
No. a future moves itself to the continuation so you can not associate twice a continuation. You need to use shared_future. Please, create a ticket. I will look for where this is said, and try to be more explicit so that the next one doesn't miss the specificity. The major difference between future and shared_future is that, you can get only once the value. Vicente
