rpl_misc_functions.test statement:  At line 25: query 'create table t2 like t1' cause slave to core. This may be due to freeing an invalid pointer.

*** glibc detected *** /home/ndbdev/jmiller/clones/mysql-5.1-new/sql/mysqld: free(): invalid pointer: 0x086e2d40 ***

This is a release build built with BUILD/compile-pentium-max.

Clone on my system was refreshed and rebuilt yesterday.

This does not occur if NDB is not used. 

Please contact me if more information is needed.

How to repeat:
Test break down. Create a test called rpl_ndb_1.test (or what ever you like)
source include/master-slave.inc;

create table t1(id int, i int, r1 int, r2 int, p varchar(100));
create table t2 like t1;
connection master;
DROP TABLE t1, t2;

touch ./r/rpl_ndb_1.result

./mysql-test-run --with-ndbcluster-all --ndb-extra-test  --force --mysqld=--default-storage-engine=ndb --do-test=rpl_ndb_1

Should get:
Errors are (from /home/ndbdev/jmiller/clones/mysql-5.1-new/mysql-test/var/log/mysqltest-time) :
mysqltest: At line 5: query 'create table t2 like t1' failed: 2013: Lost connection to MySQL server during query
(the last lines may be the most important ones)
