> message:
>   BUG#42640 mysqld crashes when unsafe statements are executed (STRICT_TRANS_TABLESmode)
>   
>   Mysql server crashes because unsafe statements warning is wrongly elevated to error,
>   which is set the error status of Diagnostics_area of the thread in THD::binlog_query().
>   Yet the caller believes that binary logging shouldn't touch the status, so it will
>   set the status also later by my_ok(), my_error() or my_message() seperately
>   according to the execution result of the statement or transaction.
>   But the status of Diagnostics_area of the thread is allowed to set only once.
>   
>   Fixed to clear the error wrongly set by binary logging, but keep the warning message.
