        Because of that, testing version are limited only for 5.0.2. FB 6.x currently is NOT tested.
     3. Custom driver config objects are created here, one with SubQueryConversion = true and second with false.
     
+    [18.01.2025] pzotov
+    Resultset of cursor that executes using instance of selectable PreparedStatement must be stored
+    in some variable in order to have ability close it EXPLICITLY (before PS will be freed).
+    Otherwise access violation raises during Python GC and pytest hangs at final point (does not return control to OS).
+    This occurs at least for: Python 3.11.2 / pytest: 7.4.4 / firebird.driver: 1.10.6 / Firebird.Qa: 0.19.3
+    The reason of that was explained by Vlad, 26.10.24 17:42 ("oddities when use instances of selective statements").
+    
     Checked on 5.0.2.1483-0bf2de0 -- all ok.
     Thanks to dimitr for the advice on implementing the test.
