non-deterministic (40% chance) workspace error: "package" is a member of the wrong workspace

[japaric]

Problem

Several Cargo commands spuriously fail within a workspace. They sometimes work fine and sometimes produce a workspace error. See the 'steps' section for the actual error message.

Steps

$ git clone https://github.com/knurling-rs/defmt
$ cd defmt/firmware/qemu
$ git checkout 00b1813

$ rustup default nightly-2022-07-11

$ # run this command ten times
# # about 3-4 of those will fail with the following error
$ cargo clean
error: package `/tmp/defmt/firmware/defmt-itm/Cargo.toml` is a member of the wrong workspace
expected: /tmp/defmt/firmware/Cargo.toml
actual:   /tmp/defmt/Cargo.toml

Possible Solution(s)

nightly-2022-07-10 and older nightlies have no issues

Notes

Also observed on GitHub Actions with Ubuntu 20.04. Build logs.

I think this was fixed in #10846

[epage]

And see #10862 for the test case.

Thanks for the report! Yea, this has been fixed by #10846. I have pushed an update, and it should be fixed in the next nightly.

Closing as fixed by #10846
