MIR Optimization panic

[Arisa-Snowbell]

when compiling mongodb-rust-driver with the latest nightly as of now (17d29dc 2022-01-21) it throws out some MIR optimization panic, i am using mongodb-rust-driver right from a repo, the commit is 577345c2b0084691882893a03a3672fdcd410e46

[lqd]

This looks like a duplicate of #93161 and will be fixed by #93165 shortly.

[lqd]

I've indeed verified that mongodb-rust-driver does not ICE with #93165 (via rustup-toolchain-master of the PR's try artifacts d634ef421795e0140724aa9fddf8137b83e616c9 ) so I'll close this issue as a duplicate.

Thanks for letting us know.
