--- Comment #2 from Richard Biener <rguenth at gcc dot gnu.org> ---
-fdisable-tree-cunroll or -fno-tree-vectorize avoid the miscompile, the key is
probably one of

t.c:7:11: optimized: loop with 14 iterations completely unrolled (header
execution count 21807684)
t.c:4:5: optimized: loop with 7 iterations completely unrolled (header
execution count 29666503)
