Yesterday I tracked down a bug in one of my programs where an Unbounded
string was containing garbage and causing Index_errors.  I traced the
problem to the following code.

-- All of this code is inside a procedure of a protected object

Function Command_Buffer return Unbounded_String is

-- Command_Buffers is an array of Unbounded_strings
-- Current_Buffer is an index in this array which is the index of the
current_buffer

begin

    return Command_Buffers(Current_Buffer);

end Command_Buffer;
pragma Inline(Command_Buffer);

<unrelated procedure sniped>

Procedure Update_Buffer is

   <unrelated declares sniped>
    True_Buffer          : Unbounded_String renames Command_Buffer;

    <unrelated Declares sniped>

    Command_Buffer : Unbounded_string  := True_Buffer;

    <rest of procedure snipped>

I have fixed the code by changing the True_Buffer declaration to an
assignment as opposed to a renaming.
I was wondering such a renaming is legal in Ada 95 since True_Buffer  is an
Unbounded_String and Command_Buffer is a function.

Any help would be appricated.
