Milestone:  To Be Determined         |  Component:  thread
  Version:  Boost 1.61.0             |   Severity:  Regression
 Keywords:  memory leak future then  |
-------------------------------------+------------------------
 Since Boost 1.60, the continuation destructor is never called.

 I've reproduced the leak using Boost 1.61 with the attached program in
 following configurations:

 * GCC 5.3.0 with BOOST_THREAD_VERSION=2, BOOST_THREAD_PROVIDES_FUTURE,
 BOOST_THREAD_PROVIDES_FUTURE_CONTINUATION
 * MSVC 14.0 with BOOST_THREAD_VERSION=2, BOOST_THREAD_PROVIDES_FUTURE,
 BOOST_THREAD_PROVIDES_FUTURE_CONTINUATION
 * MSVC 14.0 with BOOST_THREAD_VERSION=4

 Interestingly, the leak disappears with GCC 5.3.0 when
 BOOST_THREAD_VERSION=4.

 Also, there is no leak in any configuration for deferred launch policy.
