#13420: small_vector - invalid move constructor/move assignment for size < N
--------------------------------+---------------------------
 Reporter:  Antervis            |      Owner:  Ion Gaztañaga
     Type:  Bugs                |     Status:  new
Milestone:  To Be Determined    |  Component:  container
  Version:  Boost 1.65.0        |   Severity:  Problem
 Keywords:  small_vector, move  |
--------------------------------+---------------------------
 When **small_vector** is move-constructed or move-assigned from another
 **small_vector**, the initial one has elements moved out, but vector size
 is left unchanged. This only happens if internal vector memory is used
 (vector size is less than in-place capacity N)

 {{{
 small_vector<int, 5> a = {1,2,3};
 small_vector<int, 5> b = std::move(a);
 // after the assignment, a.size() is 3
 }}}

 Detailed example is [https://wandbox.org/permlink/j8fRFEpWcj9Iaz6x here].
