The usual reason for this is that some other part of your application has corrupted the heap and SQLite has stumbled over the damage. I also observe the SQLite 3.7.10 is over 5 years old. There have been 67 subsequent releases. Version 3.17.0 use less than half the CPU cycles as 3.7.10 and is completely backwards compatible. -- D.

Please check to see that the parameter you’re passing to sqlite3_db_release_memory() is the connection, not the statement. If that’s not the problem, then for debugging purposes can you try reversing the order of the last two steps ? Finalize the statement before you release memory for the connection.
