Note this only happens with --disable-checking.
#ifdef ENABLE_CHECKING
   int vectorization_factor = LOOP_VINFO_VECT_FACTOR (loop_vinfo);
#endif
...

   if (LOOP_VINFO_NITERS_KNOWN_P (loop_vinfo)
       && (LOOP_VINFO_INT_NITERS (loop_vinfo) % vectorization_factor != 
0))
     vect_transform_for_unknown_loop_bound (loop_vinfo, &ratio, loops);
...

Note the use that is not wrapped with #ifdef ENABLE_CHECKING.
The fix would be get rid of the wrapper around vectorization_factor.
