--- Comment #4 from Richard Biener <rguenth at gcc dot gnu.org> ---
Note the immediate use verification error is

      /* Avoid infinite loops.  50,000,000 uses probably indicates a
         problem.  */
      if (count++ > 50000000)
        goto error;

which is spurious, the issue is SLSR creating a gigantic function from nothing.
