MPI_ERRORS_ARE_FATAL, so codes which were sending warnings may start failing.
Model-Checker:
+ - Bump our requirements to C++14 for the model-checker. This is
+ because of xxHash that we now use as a hash implementation.
- Option model-checker/hash was removed. This is always activated now.
- New option smpi/buffering controls the MPI buffering in MC mode.
- MPI calls now MC_assert() that no MPI_ERR_* code is returned.
