Thank you for the feedback. In which tree had you seen such failures? I only found valgrind failures for this bug in mysql-trunk, but because another reason. I also found no test rpl_heartbeat_basic in 5.1

Verified as described and discussed on IRC. Problem is not particular test which fails, but code in include file. Test case: create table t1(f1 int); create table t2(f1 int); create table t3(f1 int); create table t4(f1 int); create table t5(f1 int); create table t6(f1 int); create table t7(f1 int); create table t8(f1 int); create table t9(f1 int); create table t10(f1 int); create table t11(f1 int); create table t12(f1 int); drop table t1; drop table t2; drop table t3; drop table t4; drop table t5; drop table t6; drop table t7; drop table t8; drop table t9; let $status_var_value= query_get_value(SHOW STATUS LIKE 'Com_drop_table', Value, 1); let $status_var= Com_drop_table; let $status_var_comparsion= >; drop table t10; drop table t11; drop table t12; --source include/wait_for_status_var.inc --echo Com_select event received --echo $status_var_value SHOW STATUS LIKE 'Com_drop_table';

Result in my case: **** ERROR: failed while waiting for Com_drop_table 9 **** Note: the following output may have changed since the failure was detected **** Showing STATUS, PROCESSLIST **** SHOW STATUS LIKE 'Com_drop_table'; Variable_name Value Com_drop_table 12 But 12 > 9

Gah, yes I see you have to do something of the sort to be able to support string values. Alternatively, you could check $_show_status_value for "numberness" and if it's not a number, do let $_show_status_value= '$_show_status_value'; Then you can use the unquoted variable in the test, simplifying that code. The one place I found where a string is actually used: suite/rpl/t/rpl_semi_sync.test:let $status_var_value= OFF; This would need to be changed to 'OFF'.
