#11612: serializing vector
-------------------------------+---------------------------
 Reporter:  thetetrismaster@…  |      Owner:  ramey
     Type:  Bugs               |     Status:  new
Milestone:  To Be Determined   |  Component:  serialization
  Version:  Boost 1.58.0       |   Severity:  Problem
 Keywords:  vector             |
-------------------------------+---------------------------
 In  <boost/serialization/vector.hpp>
 when dispatching to the default load method and
 detail::is_default_constructible<U> fails, should the vector be cleared if
 it is not empty? line 98 reserves capacity for the vector and line 102
 pushes new elements into the vector.  so if the vector is loaded multiple
 times its size will grow.  if you try to load a vector starting with a
 vector that is not empty, the vector size will grow.

 should you do the following check:

 if(!t.empty()) t.clear();
 t.reserve(count);
