Running cargo clippy on the crates.io codebase, I'm running into an ICE that appears to be fixed by this clippy commit: fix ice when checking rustc libstd · rust-lang/rust-clippy@572c405 · GitHub

I'm seeing the same failure on rustc 1.53.0-beta.12 (e7a67cc91 2021-06-12). The issue is resolved on nightly.

thread 'rustc' panicked at 'index out of bounds: the len is 0 but the index is 0', src/tools/clippy/clippy_lints/src/matches.rs:1595:53
note: run with `RUST_BACKTRACE=1` environment variable to display a backtrace

error: internal compiler error: unexpected panic

note: the compiler unexpectedly panicked. this is a bug.

note: we would appreciate a bug report: https://github.com/rust-lang/rust-clippy/issues/new

note: Clippy version: clippy 0.1.53 (dbe03e2 2021-06-15)

#0 [analysis] running analysis passes on this crate

Thanks for testing! I've put up [stable] 1.53.0 release - backport by Mark-Simulacrum · Pull Request #86390 · rust-lang/rust · GitHub which -- if we choose to use those artifacts -- should be ready in time for the release tomorrow, hopefully. I am currently planning to use the new set of artifacts since the backport seems extremely low-risk, but the decision will be made tomorrow morning.

I found a bug affecting this release (fmt no longer finds modules inside inline modules · Issue #9591 · rust-lang/cargo · GitHub), but that doesn't seem severe enough to be a blocker.
