Mine.  Probably a similar issue to that I have already fixed (versioning
checks?).

--- Comment #2 from Richard Biener <rguenth at gcc dot gnu.org> ---
Indeed.

  <bb 2>:
  # PT = { D.2299 } (nonlocal)
  # ALIGN = 16, MISALIGN = 0
  vectp_p.4_16 = p_7(D) + 1;
  addr2int0_4 = (signed long) vectp_p.4_16;
  andmask_3 = addr2int0_4 & 15;
  if (andmask_3 == 0)

        * tree-vect-loop-manip.c (vect_create_cond_for_align_checks):
        Make sure to build the alignment test on a SSA name without
        final alignment info valid only if the alignment test
        evaluates to true.
