#### Nightly 

The bug was introduced in `nightly-2022-11-20` (tested by bisecting nightlies from rustup). The previous day works fine.

First broken version:

`rustc --version --verbose`:
```

commit-date: 2022-11-19
host: aarch64-apple-darwin
release: 1.67.0-nightly
LLVM version: 15.0.4
```

Last working version:
`rustc --version --verbose`
```
rustc 1.67.0-nightly (b833ad56f 2022-11-18)

#### Beta
`rustc --version --verbose`:
```
rustc 1.66.0-beta.2 (0040709e3 2022-11-20)
binary: rustc
commit-hash: 0040709e39bfa159d099ee14628ad4ac72f91406
commit-date: 2022-11-20
host: aarch64-apple-darwin
release: 1.66.0-beta.2
LLVM version: 15.0.2
```

No error.

#### Stable
`rustc --version --verbose`:
```
rustc 1.65.0 (897e37553 2022-11-02)
binary: rustc
commit-hash: 897e37553bba8b42751c67658967889d11ecd120
commit-date: 2022-11-02
