#21445: add_object_page() from admin_menu action: overwrites last menu

 When the action admin_menu is fired, I have seen add_object_page()
 overwrite the last custom post type menu item. $_wp_last_object_menu is
 supposed to control this, but in this case, it failed.

 Custom post types occupied menu positions 26 - 34. then calling
 add_object_page() at admin_menu overwrote position 34.

 Changing the last post type's position to be 40 (so custom post types now
 occupy positions 26-33, 40), then add_object_page still resides in
 position 34, and the last post type still resides in 40.

 Looking at the code, I can't find the bug myself, would appreciate
 assistance in pinning down the root cause.
