--- Comment #15 from Jonathan Wakely <redi at gcc dot gnu.org> --- (In reply to Jonathan Wakely from comment #11) > Yes, it was fixed by r11-4187 but the problem is still present on the gcc-10 > branch. I think that commit simply makes it possible to use oneTBB, which doesn't give a warning. But if you use TBB 2020.3 or older, then you still get a warning.
