After running my testsuite again and next looking at
"ompi/mpi/c/comm_set_errhandler.c", I noticed that
MPI_Comm_set_errhandler() do return MPI_ERR_COMM when invalid
communicators are passed. IMHO, for the sake of consistency, you
should fix MPI_Comm_get_errhandler() to behave the same as the setter.
Would this rationale be enough?
