MariaDB CS returns wrong values if query_cache_size is turned on

If you turn on the "query_cache_size" in a MariaDB Columnstore installation, the SELECT Statements will return wrong values.

The first query will return the correct values, but after that every select query returns the values from the first (cached) query.
For Example:
Select * from A;
-> return A
Select * from B;
-> return A;
Select * from B;
-> return A;
[...]

Disconnecting does not help, since the cache remains. After the cache is invalidated (e.g. after a reboot) only the first query is correct again.
If you turn off the query cache everything works like a charm again.

Tested with version 1.1.3 and 1.1.4
