message:
  Bug #45989 take 2 : memory leak after explain encounters an
  error in the query.
  
  Fixes a leak after materializing a GROUP BY subquery to a 
  temp table when the subquery has a blob column in the SELECT
  list.
  Fixed by correctly destructing temporary buffers after doing
  the conversion.

Resetting the master before stopping the slave was generating the message
"[ERROR] Slave I/O: Got fatal error 1236 from master when reading data from
binary log: 'could not find next log', Error_code: 1236". In consequence,
the test case was failing because the message had not been suppressed.

To circumvent the failure, we rewrote the test stopping the slave before
resetting the master. We prefer this alternative rather than suppressing
the message.

in errmsg-utf8.txt, ie after ER_UNKNOWN_LOCALE.

           REORGANIZE PARTITION

There were several problems which lead to this this,
all related to bad error handling.

1) There was several bugs preventing the ddl-log to be used for
   cleaning up created files on error.

2) The error handling after the copy partition rows did not close
   and unlock the tables, resulting in deletion of partitions
   which were in use, which lead InnoDB to put the partition to
   drop in a background queue.
