MUIM_List_Move is broken

Description

The following code leads to a program crash on app close if item 0 is active:

DoMethod(list, MUIM_List_Move, 5, MUIV_List_Move_Active);

It also doesn't position items correctly. To reproduce, run the Hollywood applet attached to this ticket, select item 0 and then hit the button. You will see that the item order is not correct. Additionally, the program will crash the system when you try to close the window.

On MUI 3.8 it works fine.

It seems the simple loop for moving the elements having been replaced by a memmove() call is the culprit.

In 6296:

  • List.c: fixed the broken MUIM_List_Move implementation. The previous memmove() call corrupts memory for unknown reasons. Hence the old loop based movement has been restored. This closes #380.
