There's a failure in hyper:

   Compiling hyper v1.4.1 (/home/runner/work/tokio/tokio/hyper)
error: unreachable pattern
   --> src/proto/h2/client.rs:725:21
    |
725 |                     Ok(never) => match never {},
    |                     ^^^^^^^^^ matches no values because `Infallible` is uninhabited
    |
    = note: to learn more about uninhabited types, see https://doc.rust-lang.org/nomicon/exotic-sizes.html#empty-types
    = note: `-D unreachable-patterns` implied by `-D warnings`
    = help: to override `-D warnings` add `#[allow(unreachable_patterns)]`

error: could not compile `hyper` (lib) due to 1 previous error

Was already fixed in hyperium/hyper#3735 but not yet released.

Interesting ... The 32-bit FreeBSD build fails with a segfault:

Previously the CI run failed while running our macro tests. I changed it to run the main Tokio crate tests instead, and some tests passed, but the test eventually failed:

test util::linked_list::tests::remove_by_address ... ok

test util::memchr::tests::memchr_empty ... ok
