Crash Data


(2 files)

Attached file File with embed tag.
I saved a page which had an embedded youtube video. When I open the page, I crash.

I narrowed down the html to (in its entirety):

<embed src="THEGpbnp1tMhlen" type="application/x-shockwave-flash">

The "THEGpbnp1tMhlen" src is flash binary data saved when I saved the page. If I leave out the src attribute, it doesn't crash so I need an html page with just the above embed tag and the flash data.

I have good crash data at

I'm running Mozilla/5.0 (Macintosh; U; Intel Mac OS X 10.5; en-US; rv:1.9pre) Gecko/2008050104 Minefield/3.0pre on OS X 10.5.2. My Flash plugin is version 9.0 r124, which is the latest version.

Steps to Reproduce:
1. Save the two attached files to a local system.
2. Open the embed.html file in Firefox.

Result: crash
Attached file binary flash data

Summary: Crash when opening saved page containing youtube video → Crash when opening saved page containing youtube video [@ _CopyCStringToPascal]
WFM, same build/Flash-plugin/OSX versions as above. (also WFM in debug build)

Al, do you crash in safe-mode too?
Tomcat repro'd the crash with a normal build using the same flash and OS X version.

I didn't use Safe Mode because it was a brand new and clean profile with no extensions or themes...
Oh, and Tomcat mentioned that his debug build wouldn't crash even though the normal one did on the same machine.
