What did you do?

Unfortunately, I wasn't able to dig much into the root cause or figure out how I could possible provide a minimal reproducible example, so I'm just gonna share here what I have. Feel free to point me towards ideas for how I can break this down.

I'm running the following:

go test -v ./internal/commands/ci/status -run=TestCiStatusCommand_NoPrompt -count=1 -timeout=5s

In this Git revision: https://gitlab.com/gitlab-org/cli/-/merge_requests/2432/diffs?commit_id=b427ce280051236b9f2badd867a9150fd1f9d51a

To summarize: this is a unit test that executes a cobra command and expects it to complete.

What did you see happen?

The aforementioned test hangs forever (sometimes and not for everyone, but pretty consistently in my case), with a -timeout it eventually exists with the following:

=== RUN   TestCiStatusCommand_NoPrompt
--- PASS: TestCiStatusCommand_NoPrompt (0.00s)
PASS

What did you expect to see?

I expected the go test command to return successfully after the test completed.

cc @golang/runtime

It looks like goroutine 1 is stuck spinning attempting to take the lock in internal/runtime/exithook.Run. There are no other goroutines in functions that take this lock, so this looks impossible.

Is this reproducible?

[prattmic]

Also, was this binary built with coverage enabled? I believe coverage is the only user of internal/runtime/exithook.

@timofurrer I was suffering from the same problem and tracked it down to a bug in a library we're both using. My quick analysis in gosuri/uilive#44 .
