Problem with To_Char string overflow (6502) error

Hi,
I've condensed my problem into a very simple procedure.  Here is the procedure:

CREATE OR REPLACE PROCEDURE test IS
    iunique         integer;
    vfour           varchar2(4);
    vfive           varchar2(5);
BEGIN
   iunique := 1330    ;
   vfive := to_char(iunique,'0009') ;
   vfour:= to_char(iunique,'0009') ;
END test;


When I execute this procedure, I get a 6502 error on the line using the to_char function with vfour.  The to_char line with vfive gives no error.

As I interpret things, I am converting a four-digit integer value to characters.  This should give me a four-character result.  

Shouldn't the four-character result fit in a four-character field?  

Any explanations as to why I'm getting the 6502 error when I'm trying to put the result in a four-character field, but no error when I put the result in a five character field?

(We're using Oracle 11g by the way)
