Received signal Segmentation fault (11) when ALTER TABLE for dictionary

[infisamk]

Clickhouse server drops when I send ALTER TABLE request with COMMENT COLUMN for DICTIONARY.

I know the request is incorrect. But instead of returning the error, the server simply stops working.

Server version: (version 21.12.2.17 (official build))

Reproduce:

1. Create any dictionary. Example:

CREATE DICTIONARY stores (
    storeId UInt64,
    storeName String,
    shopId UInt32,
    status UInt8,
    lat Float32,
    lon Float32,
    address String,
    storeCountry String,
    storeRegion String,
    storeCity String,
    city_id UInt32,
    email String,
    storeParams String
)
PRIMARY KEY storeId
SOURCE(MYSQL(
    port 3306
    user 'user'
    password 'pass'
    replica(host '10.20.20.12' priority 1)
    db 'db'
    table 'stores'
))
LAYOUT(FLAT())
LIFETIME(300);

2. Send ALTER TABLE for this dictionary. Example:

ALTER TABLE stores COMMENT COLUMN storeId 'any comment';
