tests/ui/attributes/unix_sigpipe/unix_sigpipe-inherit.rs no longer passes locally

I checked out the master branch and ran ./x.py test ui and the test failed:

I am having the same problem on aarch64-apple-darwin.
cc @Enselic, this started with #123316.

@ehuss @matthiaskrgr I can't reproduce this in a clean ubuntu container. Can you? If not, probably something specific about your environments is causing this? The test did pass bors, after all.

docker run -it ubuntu

apt-get update -y && apt-get install -y git python3 curl build-essential
git clone --depth 1 https://github.com/rust-lang/rust.git ; cd rust
./x test --set rust.verbose-tests=true tests/ui/attributes/unix_sigpipe/unix_sigpipe-inherit.rs

running 1 tests
test [ui] tests/ui/attributes/unix_sigpipe/unix_sigpipe-inherit.rs ... ok

This is also happening in dev-desktop-us-1.infra.rust-lang.org, where would be easy to reproduce I guess.

[ehuss]

I think it might be an issue with caching, perhaps of the aux-bins. The following should reliably reproduce it:

apt-get update -y && apt-get install -y git python3 curl build-essential
git clone https://github.com/rust-lang/rust.git
cd rust
git checkout 7bb4f0889e8b133c5b03c46f31f2ae6432c00219
./x test tests/ui/attributes/unix_sigpipe
git checkout ce609db948f210807f61da999c57bd4ae5216254
./x test tests/ui/attributes/unix_sigpipe

[Zalathar]

If I do this, the test goes from failing to passing:

rm -r build/aarch64-apple-darwin/test/ui/attributes/unix_sigpipe/unix_sigpipe-inherit/auxiliary
x test tests/ui/attributes/unix_sigpipe/unix_sigpipe-inherit.rs

So yeah, looks like a problem with cache invalidation of something in that directory.

[Enselic]

Thanks for the reproducer. This fixes it for me: #124505

The failure is because there is an old .so file lying around: ./build/x86_64-unknown-linux-gnu/test/ui/attributes/unix_sigpipe/unix_sigpipe-inherit/auxiliary/libsigpipe_utils.so

It should use: ./build/x86_64-unknown-linux-gnu/test/ui/attributes/unix_sigpipe/unix_sigpipe-inherit/auxiliary/bin/libsigpipe_utils.so

By removing the old and obsolete file, the test passes.
