control reaches the end of non-void function means that the
last statement in your function is not a return statement.  The
only situation in which this is acceptable is if your function
never returns  from the end (e.g., because it calls exit, or
because it returns from the middle of an otherwise infinite
loop).    Is MPI_Finalize() one of these functions?

You can keep the compiler happy by putting a return
statement in anyway even though the code is not
reachable.
