No, I mean I don't understand why this:

S : constant char_array := "hello" & char'val(0);

Produces the statically allocated string without using the secondary stack.
I know that using to_c will utilise it. Unsurprised the compiler doesn't
think that string is of type string. I tried something similar without the
end from the ampersand onwards and it complained of different types.
