--- Comment #7 from Jakub Jelinek <jakub at gcc dot gnu.org> ---
I'd say it is fine for test to be optimized to 1 at -O2, but am not sure we
want to do that even for -O0 (and if we disable it for -O0, whether we want it
for -Og).  Then it will be user's choice whether he wants to instrument
optimized code (where there is no out of bound access), or non-optimized code
(where there would be out of bounds access).
