! Inconsistent handling of bad (invalid) LOGICAL kinds

! Reporter: Harald Anlauf 

! Testcase altered by Steven G. Kargl

program gfcbug57

  implicit none

  !

  ! These are logical kinds known by gfortran and many other compilers:

  !

  print *, kind (.true._1) ! This prints "1"

  print *, kind (.true._2) ! This prints "2"

  print *, kind (.true._4) ! This prints "4"

  print *, kind (.true._8) ! This prints "8"

  !

  ! These are very strange (read: bad (invalid?)) logical kinds,

  ! handled inconsistently by gfortran (there's no logical(kind=0) etc.)

  !

  print *, kind (.true._0)   ! { dg-error "kind for logical constant" }

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

  print *, kind (.true._123) ! { dg-error "kind for logical constant" }

  !

  ! Here gfortran bails out with a runtime error:

  !

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

end program gfcbug57
