Wait that other python package besides gevent you linked the according issue/pr "fixed" it by adding that flag. So I assumed "ok, -fno-fast-math doesn't override -Ofast, but then -fno-unsafe-math-optimizations surely does if they use this. No way they also just randomly add a flag and hope for the best" Do people ever actually test their fixes?
