[Bug fortran/41586] New: [OOP] Allocatable _scalar_ TYPE/CLASS leak memory

[burnus at gcc dot gnu dot org]

(Cf. also PR 41585)

type t0
end type t0
type t
  integer :: i
  class(t0), allocatable :: foo
end type t
type(t) :: m
allocate(t0 :: m%foo)
m%i = 5
end

leaks memory:

    D.1375 = (void * restrict) __builtin_malloc (1);
    m.foo.$data = (struct t0 *) D.1375;
  m.foo.$vindex = 1;
  m.i = 5;
}


SAME FOR:

type t0
end type t0
class(t0), allocatable :: m
allocate(t0 :: m)
end

AND ALSO FOR:

type t0
end type t0
type(t0), allocatable :: m(:)
allocate(t0 :: m(3))
end
