--- Comment #2 from Dominique d'Humieres <dominiq at lps dot ens.fr> ---
> Can you please bisect SVN revision that is responsible for these failures?
The warnings are issued by dsymutil coming with Xcode 7 for darwin14 or 15. If
I replace it with dsymutil coming from Xcode 6.2, the warning are gone.
And the warnings are there from 4.8 up to trunk (with variations).
