      Description

      I made backup from 10.1.28, and have made some changes because there is a new reserved keyword "rows".
      I download mariadb-10.2.12-winx64.msi installer and imported the backup, it was O.K. after a while the server reserved a lot of memory and crashed it.
      It seems that it is related with:
      profileringtransfer.controlled_profile_id in (SELECT originalid FROM tmp_profileid_cloneid)

      After some try I see that in 10.2.2 it was good, from 10.2.3 there are failures.

      How to reproduce:
      1. Install mariadb-10.2.12-winx64.msi. Nothing changed during the process.
      2. I personally used Mysql Workbench login as root.
      2. Create database osx;
      3. use osx;
      4. import database Dump20180119-2.zip
      call stored procedure:
      5. Call create_profile_working_copies('8589937224');
      after a while a response came
      Error Code: 2013. Lost connection to MySQL server during query
      run out of memory and Mariadb stopped.

      If you want to reproduce again you have to import again the database and call again
      Call create_profile_working_copies('8589937224');

      The scenario is always reproducable.
      I enclosed show_variables.txt, my.ini, errolog and hardware configuration.
      I put database dump, into ftp.askmonty.org today as Dump20180119-2.zip.

      Here is the exception:

      2018-01-22 14:38:14 5448 [ERROR] mysqld.exe: Out of memory (Needed 3828848512 bytes)
      2018-01-22 14:38:14 5448 [ERROR] mysqld.exe: Out of memory (Needed 3828848512 bytes)

      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.
       
      To report this bug, see https://mariadb.com/kb/en/reporting-bugs
       
      We will try our best to scrape up some info that will hopefully help
      diagnose the problem, but since we have already crashed, 
      something is definitely wrong and this may fail.
       
      Server version: 10.2.12-MariaDB
      key_buffer_size=134217728
      read_buffer_size=131072
      max_used_connections=5
      max_threads=65537
      thread_count=10
      It is possible that mysqld could use up to 
      key_buffer_size + (read_buffer_size + sort_buffer_size)*max_threads = 136057 K  bytes of memory
      Hope that's ok; if not, decrease some variables in the equation.
