Memory leak found in flash player active-x 'CallFunction' method.

[Guest]

Hello,

I think I found a memory leak that results from  calling the flash player active-X object's method 'CallFunction'. Each time this  method is called it seems that memory is not properly freed.

I'm attaching here a  simple program I've made with C# that uses the shockwave flash object to load a  SWF and continuously perform calls to it using the 'CallFunction'. It also  displays the process memory so you can see how it's being increased after some  time running.

In the zip file, under the bin/release directory, you'll find the  compiled executable and both the test SWF (CallFunctionTest.swf) and its source (AS3 file) which is  just a dummy Sprite that exposes a callable method using the ExternalInterface.  The SWF has been compiled using Flex compiler (Version 3.3.0 build 4852).

The  leak may become more visible after some hours running. Also, it's interesting to  note that even by reloading the SWF without closing the application (by stopping  and restarting the stress in my test application) the memory is not freed.

As a reference, in my  computer (Intel Dual core E2180 @ 2Ghz) the test application's virtual memory  (VM64) increased from 192MB to 480MB in 4 hours. In Windows XP 32-bit when this value reaches 2GB the process runs out of memory and the application crashes.

Does anyone experienced the same problem?

I have Flash Player version 10,0,32,18 installed.

Thanks,

Joan

Hi,

I found this problem recently.

I embedded Flash in my Visual C++ project through ActiveX, and intensively call

ShockwaveFlashObjects::IShockwaveFlash::CallFunction().

It seems that every time I invoke this function, the memory usage of my program increase about 8kB, and never goes back again. I think this is caused by the internal memory leak in Flash.

Does adobe have any plan to fix this issue?

Have you reported it to Adobe (https://bugs.adobe.com/flashplayer/) ?

Yes, I reported it after posting to the forum:

https://bugs.adobe.com/jira/browse/FP-3149

It seems that it could be fixed (or at least the leak reduced) in the 10.1. I tested some of the 10.1 betas some time ago and didn't have the problem. Now I'm waiting to fully test the final 10.1...
