    This is rust-lang/rust#73249 and was fixed by rust-lang/rust#73257.

    @panzan or @ZhouXiaolin can either of you confirm if the crate is fixed within your envrionments?

    That version works for me on windows (1.45 nightly). I really need to upgrade that nightly :-)
    I think we can close this now.
