[Boost-users] [ptr_container] ptr_vector and ptr_circullar_buffer don't initialize PODs

ptr_vector<T>::resize creates new objects using 'new T' instead of 'new
T()', which results in uninitialized objects if T is a POD. For consistency
with STL containers (std::vector in particular) all PODs must be explicitly
initialized.

Test:
  #include <cassert>
  #include <boost/ptr_container/ptr_vector.hpp>

  int main()
  {
      boost::ptr_vector<int> v;
      v.resize(1);
      assert(v[0] == 0); // Might fail.
  }

ptr_circullar_buffer has the same problem.

I opened a trac ticket (https://svn.boost.org/trac/boost/ticket/3579) and
attached a patch to it.
