Some reductions :
$ cat z1.f90
program p
type, abstract :: t
end type
class(t), allocatable :: x, z(:)
allocate (z(1), source=[x])
end
$ cat z2.f90
program p
type t
end type
class(t), allocatable :: x, z(:)
allocate (z(1), source=[x])
end
$ gfortran-9-20181021 -c z2.f90
z2.f90:5:0:
5 | allocate (z(1), source=[x])
