Comment 1 for bug 1370002

=============== Server version
Percona-Server-5.6.20-rel68.0-657.Linux.x86_64-debug

=============== Testcase:
DROP DATABASE test;CREATE DATABASE test;USE test;
XA START'';
SET @@session.max_statement_time=65535;
create table t2(a int,b int,c int,d int,primary key(a,b),unique(d)) engine innodb partition by key(a);

Then - importantly - exit the client (no visible CLI signs), and check error log. Testcase is likely sporadic, bug highly reproducible.
