This is curious. Since a34c7ce754 curl should build without using poll and
instead use select if built with configure (and since 6aa9cfa2b also in
cmake). poll on macOS has a long and sad story so everyone is typically better
off avoiding it there.

But since you say you can reproduce on Linux too, I doubt that's the reason.

It certainly sounds like bug, but I don't recognize it as something we've
fixed.

Please file on issue on github and tell us how we can proceed to reproduce it!
