Like https://github.com/llvm/llvm-project/issues/139866 this is from a fuzzer that generates Rust MIR: https://github.com/cbeuw/rustlantis.
I've tried to reduce the MIR, but I think there's a pretty complicated structure required because I can't get the MIR very small.

The program seems to miscompile starting at `rustc -Zmir-opt-level=0 -Copt-level=1 -Cllvm-args=-opt-bisect-limit=159`
