Thanks for the report! I don't think this is an issue wasm-bindgen but rather this is an issue with the clear-on-drop crate which includes a C file that likely isn't compiled quite right for the wasm target. It looks though like that crate has a feature to avoid compiling the C, so making sure that's used should do the trick!

jup the nightly feature of ed25519_dalek works.
