Detected without "implicit none" :
$ cat z2.f90
program p
type t
integer :: a(n)
end type t
type(t) :: x = t([1, 2])
end
$ gfortran-8-20171119 -c z2.f90
z2.f90:3:19:
integer :: a(n)
1
Error: Variable 'n' at (1) in this context must be constant
z2.f90:3:19:
integer :: a(n)
1
Error: Variable 'n' at (1) in this context must be constant
Confirmed from 4.8 up to trunk (8.0). The trunk gives:
/app/example.f90:7:20:
7 | type(t) :: x = t([1, 2])
| 1
Error: Bad array spec of component 'a' referenced in structure constructor at (1)
