Cannot execute query on mixed engine tables

Columnstore is configured in my.cnf with:

infinidb_vtable_mode = 2
infinidb_compression_type = 2
...

and in Columnstore.xml with

<CrossEngineSupport>
<Host>localhost</Host>
<Port>3306</Port>
<User>root</User>
<Password/>
</CrossEngineSupport>

root has no password on localhost, as default.

Given the following mixed-engine structure:

create database testDB DEFAULT CHARACTER SET utf8 DEFAULT COLLATE utf8_general_ci;
use testDB;

CREATE TABLE `idb_expr` (
`id` BIGINT NOT NULL ,
`repositoryid` VARCHAR(255) NOT NULL,
`code` LONGTEXT NOT NULL,
`expression` LONGTEXT NOT NULL,
`hash` BIGINT NOT NULL,
PRIMARY KEY (`id`),
KEY `idb_expr_idx_1` (`repositoryid`,`hash`)
) ENGINE = InnoDB;

CREATE TABLE `cs_cond` (
`id` BIGINT NOT NULL,
`repositoryid` VARCHAR(255) NOT NULL,
`aclinstanceid` BIGINT NULL,
`expressionid` BIGINT NOT NULL
) ENGINE = columnstore;

CREATE TABLE `cs_acl` (
`id` BIGINT NOT NULL,
`repositoryid` VARCHAR(255) NOT NULL,
`type` SMALLINT NOT NULL DEFAULT 0
) ENGINE = columnstore;

the following query:

select expr1.id as expr_id, expr1.code as expr_code, expr1.expression, expr1.hash, expr1.repositoryid as expr_repo from (idb_expr expr1 inner join cs_cond cond1 on expr1.id=cond1.expressionid) inner join cs_acl acl1 on cond1.aclinstanceid=acl1.id where acl1.type=1;

causes an exception:

ERROR 1815 (HY000): Internal error: InetStreamSocket::readToMagic: Remote is closed

Is it a bug or there's something wrong in my procedure?
The output of "columnstoreSupport -a" is atthached
