Note: The commit from comment 9 fixes only the issue for non-TARGET LHS.

If the LHS has the TARGET attribute (and only* then) a version with an
additional temporary has to be used to make sure that associated pointers still
work; the standard mandates this for the case that the shape of the RHS is the
same as the one on the LHS.

(* the reason of the only is performance not semantics)
