Associated pointers in derived type? gFortran vs. Intel

I would like to check if a pointer inside a derived type has already been defined or not. I wrote the following simple code to show you my problem:

program test
implicit none

type y
    real(8), pointer :: x(:)
end type y
type(y), pointer :: w(:)

allocate(w(2))
allocate(w(1)%x(2))

write(*,*) associated(w(1)%x), associated(w(2)%x)

end program test

Compiling this code with gFortran 4.4.1 and running it on Ubuntu gives the result:

T F

whereas the same code compiled on Windows Vista with the Intel Fortran compiler 11.0 provides:

T T

The first result (gFortran) is what I am actually expecting. But the fact that the Intel compiler provides a different result makes me fear my code might not be correct. Am I doing something terribly wrong with the pointers in this example? Any idea or explanation?

Many thanks in advance for your help!
