## 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
.timer on
PRAGMA defer_foreign_keys = FALSE;
BEGIN DEFERRED TRANSACTION;
-- glob('[!0-9]', 'a')
ATTACH DATABASE (':memory:' || '') AS aux25;
-- sqlite_compileoption_used({v})
-- NOCASE
CREATE VIRTUAL TABLE t0 USING /**/ fts4("x", "y", "z");
DROP TABLE t0;
DETACH DATABASE aux25;
END TRANSACTION;
PRAGMA defer_foreign_keys = FALSE;
BEGIN DEFERRED TRANSACTION;
-- glob('[!0-9]', 'a')
ATTACH DATABASE (':memory:' || '') AS aux25;
-- sqlite_compileoption_used({v})
-- NOCASE
CREATE VIRTUAL TABLE t0 USING /**/ fts4("x", "y", "z");
