Is a dynamic array automatically deallocated when it goes out of scope?

in this example

procedure foobar;
var tab:array of integer;
begin
  setlength(tab,10);

is the array destroyed or the memory is leaking?

The memory is freed. (That is, no memory leak!)

The array is automatically freed, but I've seen obscure cases where it isn't for some reason. I solved it by setting the array to nil.
