           Summary: world leaks: 1 WebBridge object, 1 JavaScript
                    interpreter
           Product: WebKit
           Version: 420+ (nightly)
          Platform: Macintosh
               URL: several pages
        OS/Version: Mac OS X 10.4
            Status: UNCONFIRMED
          Severity: normal
          Priority: P2

        AssignedTo: webkit-unassigned at opendarwin.org
        ReportedBy: dvirasoro at mac.com


(this was originally reported in bug 7307 together with another bug, so as
suggested here it is its own bug report)

Certain webpages cause 2 world leaks: 1 WebBridge object, 1 JavaScript
interpreter. It does not always occur so it may be necessary to repeat the
procedure a few times to replicate it. However when it does it is always those
two leaks.

I have found this with many different webpages. However so far I have only been
able to reduce it to these two single webpages:
http://animeclick.nipogames.com/index.php
http://www.macworld.com/2005/01/features/preventmacdisasters/index.php
In the future I hope I can reduce it to other webpages.

To replicate it:
1-Start Safari, and close any Safari window (no leaks are reported)
2-Go to one of these webpages
3-When it has finished loading the page, close the window
4-If the leak is not reported, try again (go back to step 2) a few times

(I am currently using the latest webkit, from Feb 19th, and OS X 10.4.4)

In the next days I will try to reduce it futher.
