------- Comment #7 from rguenth at gcc dot gnu dot org  2008-12-29 18:05 -------
Even if I cannot find the proper section of the standard that says &a->b is
not considered an access it does make sense for GIMPLE to do so.  Otherwise
we cannot transform (char *)a + 4 to &a->b because the latter would be a
(possibly invalid) access while the former is not.

So, we definitely should _not_ generate a V_C_E here.
