Only at -O0?  If not probably because the testcase assumes sizeof (long) ==
sizeof (void *).

No.  It fails at all optimizations.  sizeof (long) is the same as sizeof (void
*)
on the PA.

Fixed by

2008-11-18  Jakub Jelinek  <jakub@redhat.com>

        PR tree-optimization/38051
        * gcc.c-torture/execute/pr38051.c (buf): Remove aligned attribute.
        (buf2): Removed.
        (main): Only run on little endian targets with
        sizeof (long) == sizeof (void *).  Use just one buffer, align the
        pointers at runtime.
