wasm-opt failing due to using this crate

[SailorSnoW]

Hello, thanks for this crate, this is kinda useful actually for my project when I use some enum variants types on the Rust side.
However, I don't know why, but when I use the crate on my project, wasm-pack compilation is failing on the wasm-opt passes.

here is the full logs:

Is this something known ? Maybe the crate is using some outdated or incompatible WASM stuff with wasm-opt ?
