      Description

      All similar bugs seem to be closed at the moment, with fixes pushed at least into 10.2

      CREATE DATABASE db CHARSET utf32;
      USE db;
      CREATE TABLE t (a DATE, b TIMESTAMP(6), c INT, d INT, e INT, f CHAR(8), g ENUM('foo','bar'));
      --let $datadir= `select @@datadir`
      --write_file $datadir/db/load.data

      1975-07-23,1976-05-20 01:59:19.000000,2,1,2,quxx
      1995-09-24,1973-04-03 00:00:00.000000,3,1,3,bar
      EOF
      LOAD DATA INFILE 'load.data' REPLACE INTO TABLE t FIELDS TERMINATED BY ',';
       
      # Cleanup
      --remove_file $datadir/db/load.data
      DROP DATABASE db;
      

      The test case can probably be further simplified significantly, but it's not easy without sufficient inner knowledge.
