[fpc-pascal] reference counting of multi-dimensional array

[Xiangrong Fang]

If I have this:

var
  a2: array of array of Integer;
  i, j: Integer;
begin
  SetLength(a2, 3);
  for i := 0 to 2 do begin
    SetLength(a[i], 3);
    for j := 0 to 2 do a[i][j] := 1;
  end;
  a2 := nil; <-- will this free all memory of a[0]...a[2]?
end;

Thanks!
