Correct.
Here is a small reproducer (wrong code) to experiment with :
$ cat z1.f90
subroutine s(x)
integer :: x(:)
integer :: n = size(lbound(x))
end
Should give a regular error :
$ gfortran-6 -frepack-arrays -Warray-temporaries -c z1.f90
z1.f90:4:0:
end
Warning: Creating array temporary at (1) [-Warray-temporaries]
In contrast :
$ cat z0.f90
subroutine s(x)
integer :: x(:)
integer :: n = sum(lbound(x))
end
$ gfortran-6 -frepack-arrays -Warray-temporaries -c z0.f90
z0.f90:3:29:
integer :: n = sum(lbound(x))
1
Error: Deferred array 'x' at (1) is not permitted in an initialization
