      ==25754==ABORTING
      

      To reproduce, run the following in MTR (doesn't happen reliably for me without MTR):

      # Run with --mysqld=--innodb-buffer-pool-pages --mysqld=--innodb
      SELECT COUNT(*) FROM INFORMATION_SCHEMA.INNODB_BUFFER_POOL_PAGES;
      

      Note: It only affects 5.5, and we don't fix non-security 5.5 bugs anymore, so please feel free to close as "won't fix".
