	PR fortran/56872
	* 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.
