--- Comment #5 from Martin Sebor <msebor at gcc dot gnu.org> ---
I didn't do anything to fix the test case but the warning for it is gone
because the loop isn't unrolled anymore.  I added a test but it would be good
if Richi could confirm that it's safe to expect the unroller to avoid this
problem.
