Garbage collector does not work any way

Question

when you unload some loaded swf file (Loaded with Loader
class) it's Event Listeners continue their jobs
is there anyway to solve this problem
for example please made three files
l1.fla , l2.fla , main.fla
in l1 creat a MovieClip with instance name "symbol_mc"
and type these code
this.addEventListener(Event.ENTER_FRAME,test1,false,0,true);
function test1(evt:Event){
trace("l1");
symbol_mc.addEventListener(Event.ENTER_FRAME,test2,false,0,true);
function test2(evt:Event){
trace("symbol");
in l2 only create a text to see if file is loaded
finally in main
create to buttons with instance names btn1_btn and btn2_btn
and add these codes
var lo:Loader;
var mc:MovieClip = new MovieClip();
this.addChild(mc);
function loadSomeFile(url:String) {
lo= new Loader();
this.addChild(lo);
lo.contentLoaderInfo.addEventListener(Event.COMPLETE,
movieLoaded);
lo.load(new URLRequest(url));
function movieLoaded(evt:Event) {
this.removeChild(mc);
mc = MovieClip(lo.content);
this.removeChild(lo);
this.addChild(mc);
lo=null;
btn1_btn.addEventListener(MouseEvent.CLICK,load1);
function load1(evt:MouseEvent) {
loadSomeFile("l1.swf");
btn2_btn.addEventListener(MouseEvent.CLICK,load2);
function load2(evt:MouseEvent) {
loadSomeFile("l2.swf");
create swf files l1 and l2 and then preview main
first try btn1_btn and then try btn2_btn you will see after
unloading l1 and loading l2 event listeners will continue their
jobs!!!!!!!
after loading l1 ev

Answer 1

did you checked what you write in adobe devnet?
you said i must null loader but i not only did it but also
unloaded that before but event continue his life
i think it is not error of loader class it is gc error for
another example of it's errors try this create 2 frame fla file
add one symbole in frame 2 and then add event listener to
enterframe event of symbol
with two button add navigation for going to frames one and
two
you will see each time you enter frame 2 another
eventlistener will add to symbol and for example if your listener
rotate symbol by one degree you will see each time speed will
increase because each of them rotate object 1 degree
