--- Comment #9 from Richard Biener <rguenth at gcc dot gnu.org> ---
Fixed - I do wonder why this doesn't fail on branches, we still have the same

V foo (V v)
{
  V _2;

;;   basic block 2, loop depth 0
;;    pred:       ENTRY
  _2 = MEM[(V *)&v + -1B];
  return _2;

there upon RTL expansion.  Ah, it's because tree_could_trap_p now uses
bit_field_offset, the very problem is on branches as well (maybe it's no
problem after all).
