    * frontend-passes.c (copy_walk_reduction_arg): Change argument type
    to gfc_constructor.  If it has an iterator, wrap the copy of its
    expression in an array constructor with that iterator.  Don't special
    case function expressions.
    (callback_reduction): Update caller.  Don't return early if there is
    an iterator.
