Unfortunately, I can't write any test, which can be broken in current llvm code base.

But I have faced a problem while preparing [this series of patches](https://github.com/llvm/llvm-project/pull/119359). More precisely, [Part 4](https://github.com/llvm/llvm-project/pull/119358), [test](https://github.com/llvm/llvm-project/blob/main/llvm/test/CodeGen/RISCV/rvv/rvv-cfi-info.ll). 

All in all, I think, error can reveal in any other context while code base is developing.
