At revision 169415, the following code (probably invalid)
module astronaut_class
implicit none
private ! Hide everything by default
public :: astronaut ! Expose type & constructor
type astronaut
private
character(:), allocatable :: greeting
contains
procedure :: greet ! Public by default
end type
! interface astronaut ! Map generic to actual name
! procedure constructor
! end interface
contains
function constructor(new_greeting) result(new_astronaut)
character(len=*), intent(in) :: new_greeting
type(astronaut) :: new_astronaut
new_astronaut%greeting = new_greeting
end function
function greet(this) result(message)
class(astronaut), intent(in) :: this
character(:), allocatable :: message
message = this%greeting
end function
end module
program oo_hello_world
use astronaut_class ,only : astronaut
type(astronaut) :: pilot
pilot = astronaut('Hello, world!')
print *, pilot%greet()
end program
gives and ICE
