The code should be rejected apparently, as it violates F2008 C568.
Ifort rejects it with the following message:
error #8121: A data-stmt-object shall not be a subobject of a pointer.   [I]
  data c%i /b%i/

program p
type a
integer i
end type a
type(a), target, save :: b
type(a), pointer :: c
data b%i /42/
data c%i /b%i/
print *, c%i
end
