Summary
Trying to run cargo clippy (version 1.59, macOS 12.2.1, x64) on a fresh checkout of https://github.com/printfn/fend (commit 3a392e50d45d5dce70bcdde9e22961517b895093) crashes inconsistently: after running the command 10 times (with cargo clean inbetween), it crashed exactly 5 times. It didn't used to crash on Rust 1.58.1. I have not been able to reproduce this on Linux.
The message that appears looks like this:
$ git clone git@github.com:printfn/fend.git
$ cd fend
$ cargo clippy
...
error: could not compile `fend-core`
Caused by:
process didn't exit successfully: `/Users/printfn/.rustup/toolchains/stable-x86_64-apple-darwin/bin/clippy-driver rustc --crate-name fend_core --edition=2021 core/src/lib.rs --error-format=json --json=diagnostic-rendered-ansi,future-incompat --crate-type lib --emit=dep-info,metadata -C embed-bitcode=no -C split-debuginfo=unpacked -C debuginfo=2 --cfg 'feature="default"' -C metadata=b3e47eda875b4189 -C extra-filename=-b3e47eda875b4189 --out-dir /Users/printfn/Code/fend-copy/target/debug/deps -C incremental=/Users/printfn/Code/fend-copy/target/debug/incremental -L dependency=/Users/printfn/Code/fend-copy/target/debug/deps` (signal: 6, SIGABRT: process abort signal)

error: build failed
When I tried rerunning just the clippy-driver command that failed, I got this output:

Reproducer
I tried this code: see above
I expected to see this happen: clippy runs correctly without crashing
Instead, this happened: clippy crashed
