5065,Valgrind complaint when using Boost MPI,dongryel@…,Douglas Gregor,"I am using the latest Boost library (version 1.45.0) on Ubuntu. I have built
Boost from the source using the bjam.

boost::mpi::all_reduce uses boost::mpi::broadcast which seems to generate
annoying invalid write errors under valgrind. The problem points to the
line 47 in boost/mpi/detail/packed_oprimitive.hpp in const std::size_t &size() const
function. I changed the function to:

    const std::size_t& size() const
    {
      const_cast<std::size_t &>(size_) = buffer_.size();
      return size_;
    }

and the valgrind complaint seems to be gone. Const_cast seems less than ideal, but
it fixes the problem.",Patches,new,To Be Determined,mpi,Boost 1.45.0,Cosmetic,,Boost MPI,
