Not sure why we are looking at phf; the crate I am compiling is arrow2, with feature simd, which does depend on packed_simd2.

See this log, which fails with the latest nightly, vs this log which was produced after pinning nightly.

Aha! I completely misunderstood where this issue is on. Sorry about that!
Yes, packed_simd needs an update for rust-lang/rust#88369.

Ran into this too.
