      Description

      Start MS8.0.15 with innodb-rollback-segments
      Add data in MS using sysbench
      Take full backup

      ./xtrabackup --user=root --password='' --backup --target-dir=${backup_dir}/full -S ${mysqldir}/socket.sock --datadir=${datadir}

      Start a data load on the server using sysbench
      Take incremental backup

      ./xtrabackup --user=root --password='' --backup --target-dir=${backup_dir}/inc --incremental-basedir=${backup_dir}/full -S ${mysqldir}/socket.sock --datadir=${datadir}

      Prepare the full backup

      ./xtrabackup --user=root --password='' --prepare --apply-log-only --target_dir=${backup_dir}/full

      Prepare the incremental backup

      ./xtrabackup --user=root --password='' --prepare --target_dir=${backup_dir}/full --incremental-dir=${backup_dir}/inc

      PXB crashes during prepare

      InnoDB: Assertion failure: log0recv.cc:2118:!page || page_type == FIL_PAGE_UNDO_LOG
      InnoDB: thread 140506281453312InnoDB: We intentionally generate a memory trap.
      InnoDB: Submit a detailed bug report to https://jira.percona.com/projects/PXB.
      InnoDB: If you get repeated assertion failures or crashes, even
      InnoDB: immediately after the mysqld startup, there may be
      InnoDB: corruption in the InnoDB tablespace. Please refer to
      InnoDB: http://dev.mysql.com/doc/refman/8.0/en/forcing-innodb-recovery.html
      InnoDB: about forcing recovery.
      12:14:39 UTC - mysqld got signal 6 ;
      This could be because you hit a bug. It is also possible that this binary
      or one of the libraries it was linked against is corrupt, improperly built,
      or misconfigured. This error can also be caused by malfunctioning hardware.
      Attempting to collect some information that could help diagnose the problem.
      As this is a crash and something is definitely wrong, the information
      collection process might fail.
      key_buffer_size=0
      read_buffer_size=131072
      max_used_connections=0
      max_threads=0
      thread_count=0
      connection_count=0
      It is possible that mysqld could use up to
      key_buffer_size + (read_buffer_size + sort_buffer_size)*max_threads = 0 K bytes of memory
      Hope that's ok; if not, decrease some variables in the equation.
      Thread pointer: 0x0
      Attempting backtrace. You can use the following information to find out
      where mysqld died. If you see no messages after this, something went
      terribly wrong...
