#11830: small_vector move is broken

     Type:  Bugs                         |     Status:  new
Milestone:  To Be Determined             |  Component:  container
  Version:  Boost 1.59.0                 |   Severity:  Showstopper
 Keywords:  small_vector move            |
-----------------------------------------+-------------------------
 Moving a small_vector from a to b doesn't properly clear the contents from
 a. This is true for both the move constructor and operator=. See the brief
 example below:

 {{{
     boost::container::small_vector<std::unique_ptr<int>, 8> a;
     a.emplace_back(std::unique_ptr<int>{new int{1}});
     assert(a.size() == 1);

     auto b = std::move(a);
     assert(b.size() == 1);
     assert(a.size() == 0); // this fails
 }}}
