What it says on the tin.

Hey @alexcrichton this looks like a real failure on macos

[9](https://github.com/WebAssembly/wasi-testsuite/actions/runs/28094696689/job/83181125805?pr=265#step:9:990)
[2026-06-24T11:21:45.826+00:00] assertion `left == right` failed
[2026-06-24T11:21:45.826+00:00]   left: Err(ErrorCode::Invalid)
[2026-06-24T11:21:45.826+00:00]  right: Err(ErrorCode::NotPermitted)

Do you want me to add this to expected failures or loosen the test and allow Invalid as well?

I will use hashes from the other PR :-)
