SQLite tries to catch that situation and report the SQLITE_MISUSE error, but there are no guarantees that doing so will work. Depending on how malloc() is implemented on your system, it might segfault instead. So: Don't call sqlite3_exec() with a closed database connection. General rule: You should never do anything to SQLite that causes it to return SQLITE_MISUSE. If you do, there is an error in your code.
