More specifically:

   1048               if (rli->remaining_in_alignment < bitsize)
   1049                 {
   1050                   /* out of bits; bump up to next 'word'.  */
   1051                   rli->offset = DECL_FIELD_OFFSET (rli->prev_field);
   1052                   rli->bitpos
   1053                     = size_binop (PLUS_EXPR, TYPE_SIZE (type),
   1054                                   DECL_FIELD_BIT_OFFSET
(rli->prev_field));
   1055                   rli->prev_field = field;
   1056                   rli->remaining_in_alignment
   1057                     = tree_low_cst (TYPE_SIZE (type), 1);
   1058                 }

The third operand of size_binop() of size_binop() at line 1053-1054 
should be rli->bitpos.
