These are old failures. The goal for this bug is to be reopened each time there's a new otherwise uncategorized runtime.throw (instead of, say, creating a new bug pointing at a test in package strings or wherever it manifested), and then we make a more specific issue for it, and close this one. And then the next time there's an uncategorized runtime.throw, watchflakes posts and reopens. So I will close this one right now.

This is #54596 . I updated pattern there.

For this issue, does watchflakes suppose to reopen it as it found a new failure? @rsc

The two netbsd-arm-bsiegert failures in November look like #57170.

[bcmills]

I've attempted to pull the failures in #55167 (comment) out to #62185. (Hopefully I got the regexp correct. 😅)

#55167 (comment) is on release-branch.go1.20. Filed as #62186.

Filed #62182 for the traceback did not unwind completely failure mode, which has also shown up in some tests on other platforms.
