--- Comment #1 from Andrew Pinski <pinskia at gcc dot gnu.org> ---
Still fails as of:
    .ident    "GCC: (GNU) 4.9.0 20131110 (experimental) [trunk revision
204654]"


I thought I saw a dup of this bug.  It is just a missed optimization at -O0
which was introduced by the addition of the CLOBBERing of local non-scalars.
