+## Summary
+<!--Explain briefly what goes wrong and explain why you believe this is a bug and not the intended behavior of SQLite (if it is not a crash).-->
+We think the "INTERSECT SELECT" statement is the issue. It is a logic bug because the output is different
+
+## Minimized query
+
+```sql
+.once log.txt
+PRAGMA parser_trace = OFF;
+PRAGMA wal_checkpoint('RESTART');
+PRAGMA trusted_schema;
+.imposter off
+CREATE TABLE T1 (
+  A VARCHAR(20) PRIMARY KEY,
+  X VARCHAR(10) UNIQUE
+);
+CREATE TABLE T2 (
+  A VARCHAR(20) PRIMARY KEY,
+  Y VARCHAR(10) UNIQUE
+);
+INSERT INTO T1 VALUES ('a', 'm');
+INSERT INTO T1 VALUES ('b', 'n');
+INSERT INTO T1 VALUES ('c', 'o');
+INSERT INTO T2 VALUES ('b', 'k');
+INSERT INTO T2 VALUES ('c', 'l');
+SELECT A FROM T1 INTERSECT SELECT A FROM T2;
+ALTER TABLE T2 ADD COLUMN extra_8207 CHAR(10);
+```

+## Actual output
+
+```sql
+0|-1|-1
+1
+b
+c
+```
+
+## Expectation

+```sql
+0|-1|-1
+0
+b
+c
