binlog_encryption.rpl_temporal_format_default_to_default failed in buildbot with timeout

    XMLWordPrintable

Details

    Description

      Normally the test takes ~1 second, so the 900-sec timeout is hardly an innocent accident.

      Output from gdb follows. The first stack trace is from the failing thread.
      The following stack traces are from all threads (so the failing one is
