There is the replication chain:

master -> slave -> slave2.

1st slave started with --default-storage=blackhole, master and slave2 use MyISAM or InnoDB as default engine.

Some UPDATE statements on master successfully go through slave but raise error 1032 (HA_ERR_END_OF_FILE for UPDATE) on slave2. The log file for slave2 is below:

Find in what follows a simpler test case to reproduce the problem:

--source include/have_binlog_format_row.inc
--source include/master-slave.inc
--connection slave
let $bhs_binlog_file= query_get_value(SHOW MASTER STATUS, File, 1);

--connection slave3
--replace_result $SLAVE_MYPORT SLAVE_MYPORT $bhs_binlog_file BHS_BINLOG_FILE
--eval CHANGE MASTER TO master_host='', master_port=$SLAVE_MYPORT, master_user='root', master_log_file = '$bhs_binlog_file';

--connection master
UPDATE t1 SET c_02 = 'G', c_01= 3 WHERE c_01 = 1;

--connection slave
--connection slave3

To reproduce the problem with the test case provided at [29 Sep 23:49] Alfranio Correia, you still need both 

  rpl_row_bhs_bug56007-slave.opt and rpl_row_bhs_bug56007.cnf

provided at [16 Aug 12:59] Serge Kozlov.

The configuration files build the following structure:

  master (myisam) --> slave (blackhole, log-slave-updates) --> slave(myisam)

After running the test case, the second slave stops because the row to be
updated is not found. This happens because there is the following entry
in the first slave's binary log

### UPDATE test.t1
###   @1=1
###   @2='G'
### SET
###   @1=3
###   @2='G'

While the master which has the correct entry, there is

### UPDATE test.t1
###   @1=1
###   @2='K'
### SET
###   @1=3
###   @2='G'

Clearly, the second slave fails because there is no row (1,'G').
