ICE on 2022-10-01 nightly

[lopopolo]

Code

Sorry for not having a minimized example. I hit this ICE on a recent PR that was merged to trunk.

Reproduction steps:

git clone https://github.com/artichoke/artichoke.git
cd artichoke
git checkout e829966939a6d8cadd8b4c3f99336d08b6bbfdd7
RUST_BACKTRACE=full cargo +nightly test -p spinoso-string
