test failure: `glue_cli_run::advanced_recursive_union` `bad status`

I encountered the following failure on main inside nix:

To reproduce:

nix develop
cargo test --release --locked

~~The reason this error slipped by CI is likely that we do not use a merge queue yet. I hope to set this up soon.~~ EDIT This error does not happen on CI. btw unix_wait_status(139) is a segmentation fault.

I'm bisecting to get a specific commit.

bisected to 1ad59c6c459d44b6a33834b42a9be6457eed12fb "Replace usages of ManuallyDrop::take with ::into_inner"

[rtfeldman]

Interesting! I'll take a look. Thanks for tracking it down!

[Anton-4]

In the case that you can not reproduce it, can you let me know where I can find the binary that test produces? It's possible that it is similar to what we have going on in #3769.

[rtfeldman]

Yeah I can't reproduce it on M1 Mac inside nix develop 🤔

You should be able to reproduce it outside the test environment with:

cargo run -- glue crates/glue/tests/fixtures/advanced-recursive-union/platform.roc crates/glue/tests/fixtures/advanced-recursive-union/src/test_glue.rs
cargo run -- build crates/glue/tests/fixtures/advanced-recursive-union/app.roc

This will generate an executable binary at crates/glue/tests/fixtures/advanced-recursive-union/app

[Anton-4]

Thanks, I'll take a look when I can.

I'm hitting this on main in my Fedora 36 + Nix environment:

This no longer occurs on my NixOS machine and fedora VM.

[kili-ilo]

Yes, same here!
