Recovery crashes after unnecessarily reading a corrupted page

Details

    Description

      The test encryption.innodb-redo-badkey was accidentally disabled until recently. Once it was enabled, it started failing randomly.

      According to thiru, the crash occurs when recovery reads a corrupted page (or a page that cannot be decrypted) for which no redo log has been buffered, via the read-ahead mechanism. In this case, recovery should simply ignore the corrupted page.
