This looks like memory corruption on RISC-V. Is there an open issue for that?

The latest failure is definitely not the same as the previous failures here. I'll close this and open a new issue.

I'll close this and open a new issue.

For the moment, to stop watchflakes from reopening issues you need to add a date predicate.
(Longer term I'd like that to become unnecessary; see #57632 (comment).)
