Use `checked_sub` to avoid index out of bounds (Fixes) #4681 (possibly) The issue likely occurs due to `lit_snip.len() < suffix.len() + 1`. You can see similar backtrace to change it to `lit_snip.len() - suffix.len() - 1000` or something then run `cargo test --release`. But I couldn't come up with the test so I'd leave the issue open if we want. changelog: Fix potential ICE in `misc_early`
