Steps to Reproduce Behavior
---------------------------

1. Create a program file named Usemem.prg with the following code:

     lnx = ''
     FOR lni = 1 TO 1000
        SET SYSMENU TO DEFA
        IF TYPE('lnx') = 'C'
           lnx = VAL(SYS(1016))
        ENDIF
        lnY= VAL(SYS(1016))
        ?ALLTR(STR(lnY - lnx))
        lnx = lnY
     ENDFOR

2. Run the program file.

3. Observe the output on the screen and note that the User Object Memory
  reported by the SYS(1016) function increases by 336 bytes in four of five
  iterations and 416 bytes on the fifth iteration.
