[FLEX-23297] Unloading SWFs does not free up memory

• Type: Bug
• Status: Open
• Priority: Major
• Resolution: Unresolved
• Affects Version/s: Adobe Flex SDK 3.2 (Release)
• Component/s: mx: SWFLoader

Description

Steps to reproduce:
1. Plays MainApplication.swf
2. Pressing the button "Load" SWFLoader loads the file TestModule.swf
3. Pressing the button "UnLoad" SWFLoader must unload
Code :loader.source = "";
loader.load();
loader.unloadAndStop();

But memory is not freed!!!
4. Click again "Load", then "UnLoad" and in textarea on the right see the memory increasing all the time.

Actual Results:
Memory is never released despite using unloadAndStop(). Profiler shows memory constantly increasing as SWF's are loaded and unloaded. Garbage collection never cleans out old swf's.

Expected Results:
Upon unloading a swf I expect memory usage to drop eventually.

Workaround (if any):
None known.
