--- Comment #25 from Dominique d'Humieres <dominiq at lps dot ens.fr> ---
I have posted the results on darwin for r250610 at
https://gcc.gnu.org/ml/gcc-testresults/2017-07/msg02582.html. I see 646
failures compared to 318 with r249104.

I am planning to open new Pos for the most offending problems.
