--- Comment #1 from Andrew Pinski <pinskia at gcc dot gnu.org> ---
      /* If we do not read indirectly there is no need for transitive closure.
         We know there is only one level of indirection.  */
      if (!(flags & EAF_NO_INDIRECT_READ))
        make_transitive_closure_constraints (indir_tem);
      gcc_checking_assert (!(flags & EAF_NO_DIRECT_READ));


Confirmed.

The assert was added in r12-5113-gd70ef65692fced so it is a regression. Maybe
from that commit id.
