--- Comment #8 from Jonathan Wakely <redi at gcc dot gnu.org> --- (In reply to Kostya Serebryany from comment #1) > one other problem would be that we have zero tests for tsan in gcc :( It would be great if someone could do something about that, even just a single test would have shown this problem, which I think has been there for at least a week.
