rustc 1.75.0-nightly (31bc7e2c4 2023-10-30)
binary: rustc
commit-hash: 31bc7e2c47e82798a392c770611975a6883132c8
commit-date: 2023-10-30
host: x86_64-unknown-linux-gnu
release: 1.75.0-nightly
LLVM version: 17.0.3
However this started happening in our nightly CI since rustc 1.75.0-nightly (608e9682f 2023-10-29) (one nightly before this one). The PR must have landed in the recent past.
