    Details

      Description

      If you use cmake -DWITH_SAFEMALLOC=OFF -DWITH_ASAN=ON and run the following:

      ASAN_OPTIONS=abort_on_error=1 ./mtr main.mysqladmin
      

      then it will fail with the following:

      10.3 e9ba165bcbb9b913411b9a366a5f21d18e313de2

      CURRENT_TEST: main.mysqladmin
      mysqltest: At line 16: command "$MYSQLADMIN --database=db1 --default-character-set=latin1 -S $MASTER_MYSOCK -P $MASTER_MYPORT  -u root --password= ping 2>&1" failed with wrong error: 134
      

      If you change the 2> redirect to a file, then that file will contain the following:

      10.3 e9ba165bcbb9b913411b9a366a5f21d18e313de2

      /dev/shm/10.3/client/mysqladmin: unknown variable 'database=db1'
