Description
What version of Go are you using (go version)?
$ go version go version go1.17.7 darwin/amd64
Does this issue reproduce with the latest release?
I have not yet tried Go 1.17.8. Will do that.
What operating system and processor architecture are you using (go env)?
The executable in question is running on darwin amd64, and is cross-compiled from linux/amd64 running on GitHub Actions.
What did you do?
Not repeatably unfortunately, but one of our Go tools will occasionally wedge. The executable is cross-compiled to darwin/amd64 from linux/amd64 in GitHub Actions.
What did you expect to see?
My application not wedging and/or an uncorrupted stack trace that I could use to debug why it is wedging.
What did you see instead?
The following stack trace produced with CTRL-\:
fatal error: notesleep not on g0
panic during panic
goroutine 0 [idle]:
