#11957: static_vector::max_size() is higher than the capacity
------------------------------+------------------------
 Reporter:  anonymous         |      Owner:  igaztanaga
     Type:  Bugs              |     Status:  new
Milestone:  To Be Determined  |  Component:  container
  Version:  Boost 1.59.0      |   Severity:  Problem
 Keywords:                    |
------------------------------+------------------------
 According to the documenetation, both static_vector capacity() and
 max_size() shall return the static_vector capacity:
 {{{
 static_vector public static functions

   static size_type capacity() noexcept;
     Returns container's capacity.
     Throws. Nothing.
     Complexity. Constant O(1).

   static size_type max_size() noexcept;
     Returns container's capacity.
     Throws. Nothing.
     Complexity. Constant O(1).
 }}}
 This makes sense since the capacity is fixed at compile time.

 However it is not actually the case


 {{{
 $ cat svect.cpp
 #include <cstdlib>
 #include <boost/container/static_vector.hpp>
 #include <iostream>

 int main()
 {
   boost::container::static_vector<char, 42> sv;
   std::cout << "sv.size(): " << sv.size()
             << "\nsv.capacity(): " << sv.capacity()
             << "\nsv.max_size(): " << sv.max_size() << "\n";
   return (sv.max_size() == sv.capacity()) ? EXIT_SUCCESS : EXIT_FAILURE;
 }
 }}}
 {{{
 $ clang++ --std=c++11 svect.cpp  && ./a.out
 sv.size(): 0
 sv.capacity(): 42
 sv.max_size(): 18446744073709551615
 }}}
 {{{
 $ echo $?
 1
 }}}
