I can't reproduce this on the latest nightly, so this seems fixed. Bisected it for fun anyways and got #119106

searched nightlies: from nightly-2024-02-15 to nightly-2024-03-04
regressed nightly: nightly-2024-02-27
searched commit range: 0ecbd06...fc3800f
regressed commit: b8de591

bisected with cargo-bisect-rustc v0.6.7

Host triple: x86_64-unknown-linux-gnu
Reproduce with:

cargo bisect-rustc --preserve --start 2024-02-15 --regress non-ice --access github

Can you still reproduce this?
