Doesn't fail on trunk since r129797:

before:

pr27549.C:58: note: create runtime check for data references *D.2383_45 and
*D.2381_41
pr27549.C:58: note: LOOP VECTORIZED.

after:

pr27549.C:58: note: not vectorized, possible dependence between data-refs
*D.2383_45 and *D.2381_41

Still fails on 4.2 branch.

the assumption was that the ICE was related to versioning-for-aliasing
(run-time dependence testing), which, now that the dependence-tester was fixed,
is not required anymore, but:

...we don't have versioning-for-aliasing in 4.2, so this loop could not be
vectorized with 4.2 (unless our dependence tester in 4.2 is able to determine
the dependence without this fix?). Interesting.

I've just tried with 4.2 on PPC from svn and it did not ICE:
./gcc/cc1plus -O3 -ftree-vectorize -maltivec ~/42/build/pr27549.C
Can we close this PR?

I've just tested it with 4.2 on x86 on it worked OK as well.
