--- Comment #4 from Andrew Pinski <pinskia at gcc dot gnu.org> ---
So in GCC 12+ after evrp
  # RANGE [0, 4294967294] NONZERO 4294967295
  _1 = (long unsigned intD.16) i_9;
  # RANGE [0, 17179869176] NONZERO 17179869180
  _2 = _1 * 4;
...
  # RANGE [1, 4294967295]
  i_17 = i_9 + 1;

So maybe this has been fix ...
