Thanks for taking the time to contribute to the jQuery project! Can you move your test case to jsfiddle? thanks!

Additionally, be sure to test against the "jQuery (edge)" version to ensure the issue still exists. To get you started, use this boilerplate: http://jsfiddle.net/FrKyN/

Open the link and click to "Fork" (in the top menu) to begin.

Thanks for your quick reply.

I forked your boilerplate and I put my code => http://jsfiddle.net/d4Rhf/1/

The memory leak still happens with the "jQuery (edge)" version.

Thanks again for following up!

Does this also happen with non-empty function bodies? I'm unable to see the memory leak myself. Do you have any more information you can provide to help expose the issue? Are you seeing memory leaking in any of the other browsers?

Replying to [comment:4 mikesherov]:

Does this also happen with non-empty function bodies?

Yes.

Are you seeing memory leaking in any of the other browsers?

No, only on IE6

Today, I updated Windows XP on my test machine and it seems that Microsoft has fixed most of the problems of IE6 with that patch http://support.microsoft.com/kb/929874.
