Segfault with final method

pwl_b — Tue, 18 Sep 2012 15:32:56 GMT

Hi, I have detected, what I believe, is a bug in ifort (13.0.0 20120731). The following code produces a segfault for no reason known to me.

module mod_b

type :: b
   contains
     final :: finalize
end type b

contains

subroutine finalize(self)
    type(b) :: self
end subroutine finalize

end module mod_b

module mod_t

use mod_b

type :: tt
   contains
     procedure :: get
end type tt

contains

subroutine get( self, box)
    class(tt), target :: self
    type(b), pointer, intent(out), optional :: box
    if( present(box) ) nullify(box)
end subroutine get

end module mod_t

program d1

use mod_t
type(tt) :: t
call t%get()

end program d1

When any of the options "pointer, intent(out), optional" are altered or removed the segfault disappears.

Regards,

Paweł Biernat.
