Obviously you are not familiar with Ada RM speak:

"Not supported" means: Upon execution of your program, it's undefined what will happen.
If your compiler does not pass the argument with a valid address, your program is erroneous.
Full stop.

The RM also makes a distinction between "undefined" and "implementation defined".

But your program is legal syntax, so the compiler cannot reject it. As it cannot reject X := 1 / 0;

It might do you a favour and output a warning, though, but that's not required.
