Version it worked on

It most recently worked on: 1.83.0

Version with regression

Using rustc 1.84.0-beta.4 in crater #134138.

@rustbot modify labels: +regression-from-stable-to-beta -regression-untriaged

[cuviper]

This is kinda similar to #134707, in that it's cause by glob imports and a new unstable API.
(i.e. hash_map::Entry is long stable, but hash_set::Entry is new)

[Amanieu]

We discussed this in the libs-api meeting today. As there is only one broken crate and it isn't published on crates.io we consider this to be acceptable breakage.
