--- Comment #1 from Jerry DeLisle <jvdelisle at gcc dot gnu.org> ---
I was playing around with this just to see what happens:

program test_time_and_date
    character(8)  :: date
    character(10) :: time
    character(5)  :: zone
    integer(2),dimension(8) :: values
    ! using keyword arguments
    call date_and_time(date,time,zone,values)
    call date_and_time(DATE=3Ddate,ZONE=3Dzone)
    call date_and_time(TIME=3Dtime)
    call date_and_time(VALUES=3Dvalues)
    print '(a,2x,a,2x,a)', date, time, zone
    print *, "---------------------"
    print '(8i5)', values
end program test_time_and_date

Using integer(2):

$ gfc -g -static pr96580.f90=20
$ $ gfc -Wall -fcheck=3Dall pr96580.f90
$
 Compiles without indication of an issue.

 However, segfaults. Not really surprising, but maybe we ought to detect or
reject the code.
