--- Comment #13 from Andrew Pinski <pinskia at gcc dot gnu.org> ---
So I think the way offset_type is used here is incorrect.



  boost::interprocess::offset_ptr<T> allocate( std::size_t n ) {
      return boost::interprocess::offset_ptr<T>(a.allocate(n));
  }

That stores the offset from the stack object to the allocated memory.
That is wrong.

I am suspecting there is still some oddness going on because we optimize exact
divide better now.
