Doesn't fail on trunk since r129797:

2007-10-31  Sebastian Pop  <sebastian.pop@amd.com>

        PR tree-optimization/32377
...

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.
