--- Comment #1 from Richard Biener <rguenth at gcc dot gnu.org> ---
-fno-loop-interchange also fixes it and -fdisable-tree-vect does not, disabling
vectorization also disables the interchange (likely due to different PRE).
So this looks like a bug in loop interchange (IIRC there are some other bugs
about loop interchange).
