Is this repeatable every time innodb_priority_cleaner is ON? Is this repeatable with Percona Server?

The mutex fields look the same as in bug 1291202 (lock word = 0, waiters = 1, high priority waiters > 0), suspect it's the same underlying issue.

Hi,

This is repeatable only on debug build and not every time. I have not tested Percona server, I agree that this looks similar to #1291202.
