The last two checkouts I installed both failed passing strings through boost::mpi communication methods when the element type was not char.

I assume this way of passing strings isn't here to stay anyway since boost::serialization also handles strings.

Could you please file this as a bug report so that it (and the patch) can be kept track of? Thank you. -- Jeremiah Willcock

Unfortunately Boost.Serialization treats strings as "fundamental types", meaning every archive needs to implement serialization of strings. Your patch needs to replace MPI_CHAR by the appropriate MPI type. I'll apply the correct patch. Matthias
