R528 for F2003 is

> R528 data-i-do-object is array-element
>                       or scalar-structure-component
>                       or data-implied-do

It differs from F95

> R534 data-stmt-object is variable
>                       or data-implied-do

None of them rules out data-implied-do, so I think g95 is wrong (it still
rejects the code if I replace '8*0' with '4*0'.

I have no doubt that

 TYPE T1
  INTEGER :: I(2)
 END TYPE T1
 TYPE(T1) :: D(4)
 DATA (D(i)%I,i=1,4) /4*0/
 END

is valid and I did not find where n*v for n>'number of elements to initialize'
is forbidden by the standards.

Closing as INVALID.

it is R528 in the section on the data statement of the F2003 standard that
suggests this has to be a scalar-structure-component. Not so obvious why, if
you ask me.

just a question. why is this illegal ?

g95 emits a hard error on this one, while Intel accept it.

$ g95 a.f90
In file a.f90:5

 DATA (D(i)%I,i=1,4) /8*0/
        1
Error: Array section not allowed in DATA statement at (1)
