Test program

program largeint
  integer,parameter :: k10 = selected_int_kind(10)
  integer(kind=k10) :: i10
  i10 = 9223372036854775807
  write(*,*) huge(i10)==9223372036854775807
end program largeint

$ gfortran largeint.f95
largeint.f95:5.28:

   i10 = 9223372036854775807
                           1
Error: Integer too big for its kind at (1)

But huge(i10)==9223372036854775807 is true. The selected integer kind=8 have a
range up to 2^63-1=9223372036854775807. Even using smaller values, say
4294967295 (within the range of kind=4), gives the same error.
