        * trans-expr.c (gfc_conv_gfc_desc_to_cfi_desc): Correct the
        assignment of the attribute field to account correctly for an
        assumed shape dummy. Assign separately to the gfc and cfi
        descriptors since the atribute can be different. Add btanch to
        correctly handle missing optional dummies.
