replication slave crash with multiple xa storage engines

when running mariadb 5.5.24 with innodb and pbxt storage engines, a simple transaction crashes the replication slave. what do you suppose is happening?

we really are trying to get innodb and tokudb to work together, but they have same problem. so, we include the innodb and pbxt example below.

we grabbed the mariadb 5.5.24 source and built it with the pbxt storage engine. we then created a master slave replication environment with pbxt on and row based replication.

the crash occurs at mariadb-5.5.24/sql/log.cc:7428. note that cache_nmgr = 0.

the following crashes the slave:

create table t1 (a int primary key) engine=innodb;

create table t2 (a int primary key) engine=pbxt;

set autocommit=0;

insert into t1 values (1);

insert into t2 values (2);

commit;
