Simplified test case:
CREATE TABLE t1(a);
CREATE VIEW v2(b) AS WITH t3 AS (SELECT b FROM v2) VALUES(1);
ALTER TABLE t1 RENAME TO t4;
Notice how the definition of the V2 view refers to itself. The ALTER
TABLE command was
3.30.1 x86_64 Linux
Same problem here.

I haven’t tested many versions. But the most up-to-date master branch and the
release version has this bug.

Hi,
We found one crash bug in sqlite, which causes a dead loop and then OOM.
CREATE TABLE v0 ( v1 ) ;
CREATE TABLE v2 ( v3 ) ;
CREATE VIEW v4 AS WITH x AS ( SELECT x () OVER( ) FROM v4 ) SELECT v3 AS x FROM
v2 ;
DROP TRIGGER IF EXISTS x ;
ALTER TABLE v2 RENAME TO t3;
The bug exists
