Oh boy, now we both look silly :) I glanced at this for a while and thought
it looked funny. But I use std::vector so much and not new / delete[] that it
didn't click.
That does indeed fix things.

What I currently have has your two contributed examples in a new subdirectory
(as not everybody will have MPI around) and that use the Makefile below. Can
you try that? It uses mpic++ -showme:.... to extract the proper values for
the header files and libraries. That works for me with Open MPI. Can you try
it?

Awesome, thanks. We will of course give you proper credits for the
contribution.
