Now I'm confused... :-)

What happens if I actually _want_ to reference the same string?

Say, I get some string from somewhere (say, an argument), then I should use
1 for duplicate, because it is already referenced...
like this:     
    add_index_string(return_value, 0, arg->value.str.val, 1); // $data[0] ==
Then, when I need to create the association (pointing to the same data), I
should use 0, because I don't want the data duplicated...
like this 
    add_assoc_string(return_value, "zero", arg->value.str.val, 0); //
$data["zero"] == $data[0] == '*arg->value.str.val'

This sequence is actually what I said in my first example, so do I still not
get it, or was my first example not clear enough?
What I didn't say in my first example is that I don't allocate the data
BTW, if I did allocate the data myself, and used a 0 in the first call,
should I still deallocate the data, or is this handled by the engine now?
And if I _do_ use a 1 (so it gets duplicated) then I certainly must
deallocate the date myself, right?

Cheerio, Marc.
