Yes, it was fixed by 

        * tree.c (fld_type_variant): Copy canonical type.                       
        (fld_incomplete_type_of): Check that canonical types looks sane;        
        copy canonical type.                                                    
        (verify_type): Accept when incomplete type has complete canonical type.
