--- Comment #2 from Andrew Pinski <pinskia at gcc dot gnu.org> ---
Confirmed.
When we remove:
au = (int*) &au;
The testcase works; au is otherwise unused.
I noticed that the major different between with and without that line was a
loop was unrolled and then SLP vectorized.
I have not looked into it any further really.
