+## 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).-->**No review yet**
+
+## Minimized query
+
+```sql
+CREATE TABLE t1(a INTEGER PRIMARY KEY, b TEXT, c INT, d INT);
+INSERT INTO t1 VALUES (if(-CAST(1 AS CLOB), 1, 1), 'Wernher', 10, 100);
+INSERT INTO t1 VALUES (2, 'von', 20, 200);
+INSERT INTO t1 VALUES (3, 'Braun', 30, 300);
+
+CREATE INDEX t1bc ON t1(b, c);
+
+PRAGMA writable_schema = ON;
+
+.imposter t1bc t2
+
+SELECT * FROM t2;
+
+SELECT b, c FROM t1 ORDER BY b, c;
+
+.quit
+INSERT INTO t1 DEFAULT VALUES;
+SELECT COUNT(a) FROM t1;
+SELECT COUNT(*) FILTER (WHERE b IS NOT NULL), SUM(rowid) FILTER (WHERE b > 0), COUNT(*) FILTER (WHERE 1=0), COUNT(*) FILTER (WHERE 1=1), COUNT(*) FILTER (WHERE NULL), AVG(b) FILTER (WHERE b > 0 AND b < 100), COUNT(*) FILTER (WHERE typeof(b) = "text") FROM t1;
+SELECT GROUP_CONCAT(a, '.') FILTER (WHERE a IS NOT NULL) OVER (ORDER BY a RANGE BETWEEN 1 PRECEDING AND 1 FOLLOWING) FROM t1;
+SELECT COUNT(*) FILTER (WHERE a IS NOT NULL), SUM(rowid) FILTER (WHERE a > 0), COUNT(*) FILTER (WHERE 1=0), COUNT(*) FILTER (WHERE 1=1), COUNT(*) FILTER (WHERE NULL), AVG(a) FILTER (WHERE a > 0 AND a < 100), COUNT(*) FILTER (WHERE typeof(a) = "text") FROM t1;
+```
+
+## Actual output
+
+```sql
+CREATE TABLE "t2"("b","c","_ROWID_",PRIMARY KEY("b","c","_ROWID_"))WITHOUT ROWID;
+WARNING: writing to an imposter table will corrupt the "t1bc" index!
+|   b   | c  | _ROWID_ |
+|-------|----|---------|
+| Braun | 30 | 3       |
+| von   | 20 | 2       |
+|   b   | c  |
+|-------|----|
+| Braun | 30 |
+| von   | 20 |
