Subject: bug in expr.c?

I was cleaning up warnings expr.c and believe this to be a bug.   Can
anyone that actually understands this confirm or deny this?

expand_assignment()

      if (TREE_CODE (to) == COMPONENT_REF
          && TREE_READONLY (TREE_OPERAND (to, 1)))
        {
          if (offset = 0)
            to_rtx = copy_rtx (to_rtx);

          RTX_UNCHANGING_P (to_rtx) = 1;
        }

That copy_rtx will never ever be called, right?

Is the "obvious" fix of "offset == 0" correct?

Thanx,
RJL
