Could you look into generated assembly? And check if the incorrect behavior is reproducible with other Rust versions? It's probably caused by some weird ABI issue...
We probably should simply raise compilation error when these crates get compiled on Windows, regardless whether it's MSVC or GNU toolchain.

It's the same with toolchain
