The case where I see a problem is when the actual argument is an
element of an array that is not contiguous.  If our compiler knows
that the corresponding dummy argument is a scalar, it does not
make a copy.  If it knows the dummy argument is an assumed-size
or explicit-shape array or if it does not know that the dummy
argument is not an assumed-size or explicit-shape array, it makes
a copy of the array, starting from the element specified and
ending with the last element of the array.  If the dummy argument
is not INTENT(IN), the value of the copy must be copied back to
the array on return.
