Strange, what's your rustc version?

[yonas]

@matze rustc 1.75.0-nightly (e0d7ed1f4 2023-10-01)

[matze]

I cannot reproduce the issue with neither rustc 1.75.0-beta.3 (b66b7951b 2023-11-20) nor rustc 1.76.0-nightly (a1a37735c 2023-11-23). Does it happen with a newer nightly or stable for you?

[yonas]

@matze I don't think I can get a newer version yet. Are you on FreeBSD 14.0-RELEASE as well?

[matze]

Nope, I am on Linux. And it's weird, I was trying to install your version but it does not seem to exist:

$ rustup install nightly-2023-10-01
info: syncing channel updates for 'nightly-2023-10-01-x86_64-unknown-linux-gnu'
info: latest update on 2023-10-01, rust version 1.74.0-nightly (ca62d2c44 2023-09-30)

[matze]

Could you test current master? I moved to axum 0.7 and hyper 1.0, perhaps it changes anything for you.

[yonas]

@matze It works, thanks! :tada:
