"Broken MIR" error on latest nightly

[kaimast]

When compiling lsm-rs on latest rust I get a panic.

Meta

rustc --version --verbose:

rustc 1.60.0-nightly (17d29dcdc 2022-01-21)
binary: rustc
commit-hash: 17d29dcdce9b9e838635eb0adefd9b8b1588410b
commit-date: 2022-01-21
host: x86_64-unknown-linux-gnu
release: 1.60.0-nightly
LLVM version: 13.0.0

Notes

This also happens on github actions, so I can reproduce it on multiple machines.

I can only reproduce this on the most recent nightly (2022-01-21), 2022-01-20 and earlier work fine.

The crate uses a few unstable features, that might trigger this.

I believe I'm encountering the same issue compiling tide on nightly 1.60.0.

[lqd]

These are duplicates of #93161 and are already fixed on master, but not available on nightly yet. They will be fixed in the next nightly which will contain #93165.

The most recent 2 nightlies have this issue:

• "nightly-2022-01-23" on rustup: rustc 1.60.0-nightly (bfe156467 2022-01-22)
• "nightly-2022-01-22" on rustup: rustc 1.60.0-nightly (17d29dcdc 2022-01-21).

We've checked yesterday that this PR fixes tonic, and I've now checked it fixes lsm-rs as well (via rustup-toolchain-master of PR #93165's try artifacts d634ef421795e0140724aa9fddf8137b83e616c9 ) so I'll close this issue as a duplicate.

Please reopen this issue if tomorrow's nightly doesn't fix it. There are other ICEs that it does not fix but it's expected that the 3 above will be.
