--- Comment #14 from Richard Biener <rguenth at gcc dot gnu.org> ---
It's not fully fixed unless you use generic tuning, so let's keep it open.
Mitigation in source should be to place

#pragma GCC novector

before the loop.  Note this only works for GCC 14 and up (that fix might be
backportable, see PR111125).
