The cargo test PR check is failing, but the error is different. https://github.com/danielparks/matchgen/actions/runs/4395919376/jobs/7698033263

❯ Run cargo build --tests

Error: Process completed with exit code 143.

For comparison, cargo build --tests in Docker fails with the ld errors described in this issue. It returns exit code 101.

[danielparks]

Looks like the action failure is unrelated. It only occurs with the flat-matcher change, and the relevant lines (I think) from cargo test --all-features -vv are:

So, the failure may be specific to Docker, my machine, or something else.

[danielparks]

It appears this is not related to sharing target/ with both Docker and macOS. It also appears that this does not occur on the first build, and does not occur in --release mode.

It also sometimes fixes itself, and sometimes other files are missing:

It’s not clear to me whether specifying --profile dev makes a difference or if it’s random.

[danielparks]

It appears that the problem does not occur when working in directory that isn’t shared with the host in Docker. Performance also seems to be better.

I suspect a race condition. The question is if it’s in cargo/rustc or Docker. So far I’ve had no luck reproducing the problem by just creating and deleting files.

[danielparks]

I’ve worked around the problem by forcing cargo to use a non-shared directory for build artifacts. Not closing this because it would be good to figure out where the problem is an report is.

[danielparks]

It appears that this only happens when we build matchers for all HTML entities. So, this may be caused by and out-of-memory condition, or maybe a race condition that triggers when performance is particularly bad.
