Ignore that output from Valgind. I was logged out between building and
running, and failed to reload the appropriate environment. With the correct
environment, I get a clean run from valgrind:

OK - had a bit of time waiting for the New Year countdown … so read up a bit
on valgrind.
A vanilla run under Linux with 4.9.0 gave the following, which seems
encouraging, albeit cryptic:

I have testend under OS X (10.8.5) with gfortran 4.8.1 and 4.8.2. I've also
tested under Linux (not sure which flavor) with 4.9.0.

And I just applied Aaro Koskinen's patch on gcc 4.8.2, recompile gcc and
resolve this issue.

It looks to me like the problem arises because reload selected a
call clobbered register, %r1, for reg/f:SI 2442 and there is no way to
reconstitute reg/f:SI 2442 following a call:

Something simliar happens on aarch64, but later goes ahead and vectorizes it
anyway. How about trying to vectorize on x86 with -fno-vect-cost-model?

--- Comment #1 from Bingfeng Mei ---
That is interesting. On x86-64, GCC does say it cannot determine dist vector
between a[3] & a[b] and needs run-time aliasing test. In the end it gives up
due to too few iterations.
