#12852: Resizing fills the circular buffer
------------------------------+-----------------------------
 Reporter:  b.n.ryland@…      |      Owner:  jano_gaspar
     Type:  Bugs              |     Status:  new
Milestone:  To Be Determined  |  Component:  circular_buffer
  Version:  Boost 1.63.0      |   Severity:  Problem
 Keywords:  resize, full      |
------------------------------+-----------------------------
 As the following block of code demonstrates, resizing a circular buffer
 fills it with values and thus full() reports true when one would expect it
 to be false.
 {{{
         boost::circular_buffer<double> cb(3);
         std::cout << cb.full() << std::endl;
         for (auto i : cb)
                 std::cout << i << " ";
         std::cout << std::endl;
         cb.resize(4);
         std::cout << cb.full() << std::endl;
         for (auto i : cb)
                 std::cout << i << " ";
         std::cout << std::endl;
 }}}
