Why does the following program not indicate siez=0 in the third row of output? (The smiley face in line 3, seems to be an error, the code is written as ( : ) without the spaces.)

PROGRAM p
IMPLICIT NONE
INTEGER, DIMENSION(Smile, ALLOCATABLE :: i
INTEGER :: ios
!
WRITE (UNIT=*,FMT=*) ALLOCATED(i),SIZE(i)
ALLOCATE (i(5),STAT=ios)
WRITE (UNIT=*,FMT=*) ALLOCATED(i),SIZE(i)
DEALLOCATE (i)
WRITE (UNIT=*,FMT=*) ALLOCATED(i),SIZE(i)
!
END PROGRAM p

The Fortran 95 Standard says that SIZE must not be used when the array has not be allocated. So this is essentially a programming error that is difficult for FTN95 to trap.

When I tested with /checkmate the result was zero but you may not be able depend on this.
