#9711: future continuation called twice

 Reporter:  anonymous         |      Owner:  anthonyw
     Type:  Bugs              |     Status:  new
Milestone:  To Be Determined  |  Component:  threads
  Version:  Boost 1.55.0      |   Severity:  Problem
 Keywords:  futures           |
------------------------------+----------------------
 I know it is still experimental, but I found a trivial bug in
 future::then().

 If used with the deferred launch policy the continuation is called twice:

 The first time it is called in promise::set_XXX() or future::then() as it
 should be, but it is called again in the get() method of the future
 returned by the then() method.

 You can reproduce the problem by running the attached code.
