Yes, the error field of the status type is simply not filled with any meaningful information by the send and receive type functions. It might be filled with an error code in a situation where you are waiting for the completion of multiple non-blocking point to point operations. This part of MPI is not covered by the bindings yet. (See e.g. MPI_Waitall() on the list of unfinished features in the documentation of the point_to_point module.)
More generally, however, the default behavior of MPI is to abort the program on communication errors rather than returning an error code. The bindings do not change this default at the moment.
I should probably remove the error() getter function and the error field from the Display output of Status.
