It's not safe.  You don't give the declaration of "Sub", but if it's something like

    procedure Sub (Proc : Proc_Type);

then for all the compiler knows, Sub could assign some global variable of type Proc_Type to Proc (Glob_Proc := Proc;).  Then an access to Test would exist after Accessibility_Level_Test exited, which is no good (it could be a disaster if the global variable was later used for a procedure call).
