Hi,

The sample code is here: https://gist.github.com/jamboree/3b8716ad1922749e77ae

The boost::future adaption code is adapted from N4286.

Tested with VS2015 preview. If std::promise is passed, the code works fine. Any clue why it hangs if boost::promise is passed?

Hi,

I've been working on a possible fix on this branch https://github.com/boostorg/thread/tree/fix/blocking_future.

I have found a lot of issues on the current implementation and most of them are fixed now (weel at least I think so), however I have yet some issues with shared_future::then.

Please, could you give a try to this branch?

Doesn't seem to change the behavior.

That said, I'm not sure what the correct adaption code for boost::future would be, as you guys pointed out, the code extracted from N4286 isn't quite correct. And I also found other bugs in their await implementation, but I'm not sure it's relevant to this problem...

Anyway, thanks for looking into this, though I was just playing with the proposed await, not really for practical work.

Let me know if you get something working. Vicente
