Description:
I want to ignore memory tables replication with step 2 setting in my.cnf, but if i execute the sql statement in step 5, the delete statement for memory tables(step 6) will appear in binary log.
How do i solve this problem? Can i add "replicate-ignore-db=db2" to ignore the replication in slave. Is there any other way to fix it?

FYI:

Third paragraph of functionality added or changed
Replication: For replication of MEMORY (HEAP) tables: Made the master automatically write a DELETE FROM statement to its binary log when a MEMORY table is opened for the first time since the master's startup. This is for the case where the slave has replicated a nonempty MEMORY table, and then the master is shut down and restarted: the table is now empty on the master; the DELETE FROM empties it on the slave as well.

How to repeat:
Steps to reproduce:
1.
create database db1;
use db1;
create table tb1(col1 int primary key, col2 int);

create database db2;
use db2;
create table tb1(col1 int primary key, col2 int) ENGINE=MEMORY;

2.
binlog-ignore-db = db2

3.
/etc/init.d/mysql restart

4.
mysql -u root -p[PASSWORD] db1; 

5.
SELECT * FROM information_schema.key_column_usage;

6.
check if there is below sql statement in binary log:
DELETE FROM `db2`.`tb1`
