   3 ! Inconsistent handling of bad (invalid) LOGICAL kinds

   9   ! These are logical kinds known by gfortran and many other compilers:
  10   !
  11   print *, kind (.true._1) ! This prints "1"
  12   print *, kind (.true._2) ! This prints "2"
  13   print *, kind (.true._4) ! This prints "4"
  14   print *, kind (.true._8) ! This prints "8"
  15   !
  16   ! These are very strange (read: bad (invalid?)) logical kinds,
  17   ! handled inconsistently by gfortran (there's no logical(kind=0) etc.)

  19   print *, kind (.true._0)   ! { dg-error "kind for logical constant" }
  20   print *, kind (.true._3)   ! { dg-error "kind for logical constant" }
  21   print *, kind (.true._123) ! { dg-error "kind for logical constant" }

  23   ! Here gfortran bails out with a runtime error:

  25   print *, .true._3   ! { dg-error "kind for logical constant" }
