OS: Windows 11

Python Version: 3.8+

 Description   

When running a script without closing connection and cursor python sometimes crashes when closing these objects via garbage collector (Only reproducable on Windows).

Instead of if tp_dealloc method, objects should be cleared in tp_finalize.

import mariadb
 
 
 
c=mariadb.connect(user="root", db="test")
 
cursor=c.cursor()
 
cursor.execute("select * from t1")


$ python test.py
 
Windows fatal exception: access violation
