This very short program produces an ICE with gfortran 11.2.1:

module m

    type :: item
        real :: x
    end type

    type :: container
        type(item) :: items(3)
    end type

end module

program p

    use m

    type(item), allocatable :: items(:)
    type(container) :: c

    items = [item(3.0), item(4.0), item(5.0)]
    ! ICE in the line below
    c = container(items=[(items(i), i = 1, size(items))])
    print *, c

end program
