[New-bugs-announce] [issue22272] sqlite3 memory leaks in cursor.execute

[A. Libotean]

New submission from A. Libotean:

There are significant memory leaks when multiple insert statements are executed with distinct values.

sqlite3 version is 2.6.0

The attached file contains two variants:

* one which uses string interpolation to build the query: this generates severe leakeage
* the other one is using parametrized queries and the leakeage is not as bad

I'm assuming that somehow the query string reference is not freed properly.
