#13299: small_vector<..>::emplace_back does not return the new element's reference

     Type:  Bugs                        |     Status:  new
Milestone:  To Be Determined            |  Component:  container
  Version:  Boost 1.63.0                |   Severity:  Problem
 Keywords:  small_vector, emplace_back  |
----------------------------------------+---------------------------
 I want to emplace a new item at the back of a small_vector and use the
 reference to the new item:

 {{{
 boost::container::small_vector<int,16> myVec;
 auto& newItem = myVec.emplace_back(10);
 assert(newItem == 10); /* this fails */
 }}}

 It seems like the returned reference points to the last element of the
 internal array (like myVec[15]). This element is uninitialized.
