Logical error: 'Bad cast from type DB::ColumnVector<int> to DB::ColumnNullable'. #78572
Description
Important: This issue was automatically generated and is used by CI for matching failures. DO NOT modify the body content. DO NOT remove labels.
Test name: Logical error: Bad cast from type A to B
CI report: AST fuzzer (amd_ubsan)
CIDB statistics: cidb
Describe the bug
The original error: Logical error: '(isConst() || isSparse()) ? getDataType() == rhs.getDataType() : typeid(*this) == typeid(rhs)'.
It seems not related to #75450
From this run: https://s3.amazonaws.com/clickhouse-test-reports/json.html?PR=78284&sha=e585d4785d24bf1a150dd74887c45a6405c760a4&name_0=PR&name_1=AST+fuzzer+%28ubsan%29
Seems to be a regression in the current master. Time to bisect 😄
How to reproduce
I managed to reduce it to a simple script:
CREATE TABLE t0 (k1 Nullable(Int)) ENGINE = Memory;
CREATE TABLE t2 (k1 Int) ENGINE = Join(ALL, FULL, k1);
INSERT INTO t0 VALUES (1);
INSERT INTO t2 VALUES (1);
SELECT t1.k1 FROM t0 FULL JOIN t2 t1 USING (k1) FULL JOIN t2 t2 USING (k1);
