+## 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 "COLLATE" keyword is causing bugs, it is a logic bug because the output is different
+
+## Minimized query
+
+```sql
+PRAGMA secure_delete = ON;
+CREATE TABLE t0(c0 REAL, c1 REAL GENERATED ALWAYS AS (c0));
+INSERT INTO t0(c0) VALUES (-(-(unhex(1))));
+SELECT * FROM t0 GROUP BY c0;
+CREATE TABLE t1(a, b);
+CREATE TABLE t2(c, d);
+SELECT max(t1.a), (SELECT 'xyz' FROM (SELECT * FROM t2 WHERE 0) WHERE t1.b=1) FROM t1;
+
+INSERT INTO t1 SELECT * FROM t1;
+CREATE TABLE T (
+  a INTEGER,
+  b REAL
+);
+INSERT INTO T VALUES (1,1.5), (2,-7.25), (3,0.0);
+SELECT a,b FROM T WHERE a >= 2 ORDER BY b;
+ALTER TABLE t1 ADD COLUMN extra_7155 MEDIUMINT COLLATE RTRIM;
+PRAGMA cache_spill = FALSE;
+INSERT INTO t0 DEFAULT VALUES;
+```
+
+## Actual output
+
+```sql
+1
+|
+2|-7.25
+3|0.0
+```
+
+## Expectation

+```sql
+1
+|
+|
+2|-7.25
+3|0.0
+```
