        * resolve.c (resolve_ordinary_assign): Do not add the _data
        component for class valued array constructors being assigned
        to derived type arrays.
        * trans-array.c (gfc_trans_array_ctor_element): Take the _data
        of class valued elements for assignment to derived type arrays.
