We could demote this to WARN instead of ERROR (perhaps only if everything but the inode number matches).

I'm not surprised it's still broken since we haven't done anything here, but is there a test case for this somewhere?

Keno's issue is a very specific problem, and this is a very general error message, so it would be best if you filed a new issue.

This could be related to the DOUBLE_UNDERSCORE_PTHREAD_LOCK_AVAILABLE stuff. jammy has glibc 2.35

Try doing `rr replay -g `.

That stack is just a little too far.

Are you running rr build from the latest git rev or one your distro provided? If the latter, is it reproducible on tip?
