Hi,
I'm playing flash "swf" file using WebView in my application. My application is
crashing randomly, below is the stack trace from gdb:

Program received signal:  "EXC_BAD_ACCESS".

It's very difficult to give the steps to reproduce this bug. Our is a complex
flash application, it is doing lots of thing at the time of crash, like it is
creating movie clip, communicating with flash communication server.

I've discussed this issue on WebKit list as well, below is the link for same:

http://lists.apple.com/archives/webkitsdk-dev/2006/Jun/msg00043.html.

Please let me know how can I help you in solving this bug. I've put my
application on FTP server as given in discussion on list. This bug has become
the showstopper for us as we are in the release phase. We can make our system
available on internet so that you can easily see the crash, it is very
frequently happening in our application.

Regards,
Gurmit
