#9523: reserve() corrupts data in boost::bimap vector_of_relation
------------------------------------------------+---------------------

     Type:  Bugs                                |     Status:  new
Milestone:  Boost 1.56.0                        |  Component:  bimap
  Version:  Boost 1.54.0                        |   Severity:  Problem
 Keywords:  bimap, reserve, vector_of_relation  |
------------------------------------------------+---------------------
 bimap::reserve() has bad behavior:
   1. Corrupts the data by inserting item into the empty bimap
   2. Reserves incorrect amount of elements capacity

 Environment: Linux Ubuntu x64 3.2.0-57-generic 87-Ubuntu SMP, gcc (Ubuntu
 4.8.1-2ubuntu1~12.04) 4.8.1

 Code:
 {{{
         typedef unsigned  Id;
         const unsigned  m_nodes = 1518;

         typedef boost::bimap<boost::bimaps::unordered_set_of<Id>,
                 boost::bimaps::unconstrained_set_of<Id>,
                 boost::bimaps::vector_of_relation>  Nbimap;
         Nbimap  m_nbimap;


 fprintf(stderr, "Initial bmsize: %u, capacity: %u\n", m_nbimap.size(),
 m_nbimap.capacity());
         m_nbimap.reserve(m_nodes);
 fprintf(stderr, "Postreserve bmsize: %u, capacity: %u, nsize: %u\n",
 m_nbimap.size(), m_nbimap.capacity(), m_nodes);
 }}}

 Console output:
 {{{
 Initial bmsize: 0, capacity: 0
 Postreserve bmsize: 1, capacity: 15, nsize: 1518
 }}}
