          Optional steps to reproduce the same with environs framework:

          Setup environment:

          git clone https://github.com/AndriiNikitin/mariadb-environs
          cd mariadb-environs
          # getting required plugin
          git clone https://github.com/AndriiNikitin/mariadb-environs-xtrabackup _plugin/xtrabackup
           
          # getting and building 10.2 tree
          ./replant.sh m1-10.2
          m1-10.2/checkout.sh
          m1-10.2/make.sh
          m1-10.2/build.sh
           
          # installing xtrabackup 2.4.7
          # better to install because .tar distribution typically have dependency problems 
          ./replant.sh x1-system
          sudo x1-system/install.sh 2.4.7
          

          Run the test with command below, observe Xtrabackup crash:
          ./runsuite.sh m1 x1 _plugin/xtrabackup/t/MDEV-12720.sh

          Observe that no crash happens when line "# sleep 2" is uncommented in _plugin/xtrabackup/t/MDEV-12720.sh (increase sleep amount otherwise).

          Optional - install tar 10.1.23 , 10.2.5 and 5.7.18 and observe no crash with those (undo changes to MDEV-12720.sh if any):

          ./replant.sh m2-10.1.23
          m2*/download.sh
          ./runsuite.sh m2 x1 _plugin/xtrabackup/t/MDEV-12720.sh
           
          ./replant.sh m3-10.2.5
          m3*/download.sh
          ./runsuite.sh m3 x1 _plugin/xtrabackup/t/MDEV-12720.sh
           
          # get required oracle-mysql plugin
          git clone https://github.com/AndriiNikitin/mariadb-environs-oracle-mysql _plugin/oracle-mysql
          ./replant.sh o1-5.7.18
          o1*/download.sh
          ./runsuite.sh o1 x1 _plugin/xtrabackup/t/MDEV-12720.sh

          Alternatively - test with the latest 10.2 build instead of source tree:

          git clone https://github.com/AndriiNikitin/mariadb-environs-hasky _plugin/hasky
          ./replant.sh m5-10.2~latest
          m5*/download.sh

          To start mysqld at boot time you have to copy
          support-files/mysql.server to the right place for your system
           
          PLEASE REMEMBER TO SET A PASSWORD FOR THE MariaDB root USER !
          To do so, start the server, then issue the following commands:
           
          '/home/a/test1/mariadb-environs/m5-10.2~latest/../_depot/m-tar/10.2-14294/bin/mysqladmin' -u root password 'new-password'
          '/home/a/test1/mariadb-environs/m5-10.2~latest/../_depot/m-tar/10.2-14294/bin/mysqladmin' -u root -h UBINTI password 'new-password'
           
          Alternatively you can run:
          '/home/a/test1/mariadb-environs/m5-10.2~latest/../_depot/m-tar/10.2-14294/bin/mysql_secure_installation'
           
          which will also give you the option of removing the test
          databases and anonymous user created by default.  This is
          strongly recommended for production servers.
           
          See the MariaDB Knowledgebase at http://mariadb.com/kb or the
          MySQL manual for more instructions.
           
          You can start the MariaDB daemon with:
          cd '/home/a/test1/mariadb-environs/m5-10.2~latest/../_depot/m-tar/10.2-14294' ; /home/a/test1/mariadb-environs/m5-10.2~latest/../_depot/m-tar/10.2-14294/bin/mysqld_safe --datadir='/dev/shm/__var0/var1/data'
           
          You can test the MariaDB daemon with mysql-test-run.pl
          cd '/home/a/test1/mariadb-environs/m5-10.2~latest/../_depot/m-tar/10.2-14294/mysql-test' ; perl mysql-test-run.pl

          It seems to me that the crash occurs because MySQL 5.7 (which Percona Xtrabackup is based on) is not doing a proper shutdown after a failed startup.
          Because of the failed startup, purge_sys must have been left at NULL, and then shutdown would hit SIGSEGV in the function trx_purge_state().

          The real issue seems to be the following:

          InnoDB: Doing recovery: scanned up to log sequence number 1770296 (2%)
          InnoDB: Plugin initialization aborted with error Generic error
          

          Why was the startup aborted? I cannot think of any redo log format changes between MySQL 5.7.9 and MariaDB 10.2.6, other than MDEV-11782 which changed the encrypted redo log format (which is not compatible with MySQL 5.7 to begin with). At this stage, I do not think that other file format changes (such as the transaction system state format change in MDEV-12289) would matter.

          This indicates that most probably regular crash recovery may fail on 10.2 (without backup). Marko promised to look into log file.
