Hopefully since 21.05 there will be new threading A= PI. =20 >=20 > Thanks Dmitry, it's odd that the compiler complains only now, I'd expect = to see this warning even before the change. These functions don't have "nodiscard"-like attributes, so a call without using result was OK, now it's an expression. > Do we know if the new threading API will be in 21.05? API changes close i= n 3 days and I didn't see it get reviewed/acked. > I can change only pthread_barrier_init for now, since currently without t= his change Windows runtime is broken, what do you think?=20 (You probably mean pthread_barrier_destroy(), from which the warning comes.) Yes, this is worth merging as soon as warnings are fixed. Not sure new threading API will make it into 21.05.
