Segmentation fault when inserting data #30
Description
Initially I thought that the primary key must contain at least two columns so I created a table with constant expression in primary key tuple with this query:
create table hoba (naber Date) ENGINE = MergeTree(naber, (1, naber), 8192)
The query is executed successfully and I tried to INSERT data to the table:
INSERT INTO hoba (naber) VALUES ('2010-01-01')
However this query causes ClickHouse to throw Segmentation fault and exits ungracefully:

Using constant values in primary key may be invalid but in this case Clickhouse should not allow such table definition.
