--- Comment #1 from Dominique d'Humieres <dominiq at lps dot ens.fr> ---
I see two issues with the test assign_11.f90:

(1) an ICE, reduced test

program test
  implicit none
  type t
    integer :: ii
  end type t
  type(t) :: y(3)

  y = func2()
contains
  function func2() result(res)
    class(t), allocatable :: res(:)
  end function func2
end program test

[Book15] f90/bug% gfc49 pr63205_red.f90
pr63205_red.f90: In function 'test':
pr63205_red.f90:8:0: internal compiler error: in gfc_trans_arrayfunc_assign, at
fortran/trans-expr.c:7369
   y = func2()
 ^

(2) a wrong code, reduced test

module m
  implicit none
  type t
    integer :: ii = 55
  end type t
contains
  subroutine sub (from, from2)
    class(t) :: from, from2(:)
    type(t) :: to, to2(3)

    if (from%ii /= 43) call abort()
    if (size (from2) /= 3) call abort()
    if (any (from2(:)%ii /= [11,22,33])) call abort()

    to = from  ! TYPE = CLASS
    to2 = from2  ! TYPE = CLASS

    print *, to%ii
!    if (to%ii /= 43) call abort()
    if (any (to2(:)%ii /= [11,22,33])) call abort()
  end subroutine sub
end module m

program test
  use m
  implicit none
  type(t), target :: x
  type(t), target :: y(3)

  x%ii = 43
  y(:)%ii = [11,22,33]
  call sub(x,y)
  x = func1()
  print *, x
!  if (x%ii /= 123) call abort()
  y = func1()
  print *, y
!  if (any (y(:)%ii /= 123)) call abort()
contains
  function func1()
    class(t), allocatable :: func1
    allocate(func1)
    func1%ii = 123
  end function func1
end program test

Any objection that I open a new PR for the ICE?

AFAICT the assignment works for array variable, at least in the to2 context.
