gdb stack trace of firefox signalling SIGILL

Description of problem:
Firefox fails with a SIGILL (not a SIGSEGV) when I attempt to play flash content at the URL listed (in step 3) below.

Version-Release number of selected component (if applicable):
$ rpm -q firefox
firefox-3.5.2-2.fc11.x86_64

Adobe flash player 10.0.32.18, 64-bit from:
http://download.macromedia.com/pub/labs/flashplayer10/libflashplayer-10.0.32.18.linux-x86_64.so.tar.gz

$ sha1sum libflashplayer.so
8ec78fc69293eccc6aad3cb6272ba6356a522fe0  libflashplayer.so

How reproducible:
Every time I attempt to play the content at the URL listed in the stack trace.


Steps to Reproduce:
Install Fedora 11 for x86_64.  Apply all recent updates.  Download the flash player library from the URL listed above and copy it to the directory ~/.mozilla/plugins/ (only).

At bash prompt, enter:
1. $ rm -rf ~/tmp/new-profile && mkdir ~/tmp/new-profile
2. $ cd ~/.mozilla/plugins/
3. $ /usr/bin/firefox -g -d gdb -profile ~/tmp/new-profile -no-remote 'http://www.youtube.com/falltvpreview'
  
Actual results:
Firefox fails with a SIGILL signal.

Expected results:
Play the flash content, as occurs on Fedora 10.

Some flash content does not cause Firefox/flash player to fail, for example
/usr/bin/firefox 'http://www.youtube.com/watch?v=32wIKaLkvc4&NR=1'


Additional info:
I will attach a copy of the large, multi-threaded stack trace for this failure.

Updated stack trace of firefox signalling SIGILL using Firefox 3.5.3-1

Here is an updated stack trace using Firefox 3.5.3-1.  Also, '-safe-mode' has been added to the command-line options that are passed to firefox.

$ rpm -q firefox xulrunner
firefox-3.5.3-1.fc11.x86_64
xulrunner-1.9.1.3-1.fc11.x86_64

$ rpm -V firefox xulrunner && echo $?
0

Sorry, this is a crash in the flash plugin itself with which we cannot help. You would be much better by installing libflashplugin.so to %{_libdir}/mozilla/plugins and installing nspluginwrapper (if using 32bit plugin from http://get.adobe.com/flashplayer/thankyou/?installer=Flash_Player_10_for_Linux_(YUM) then you need both 32bit and 64bit version of nspluginwrapper, if using 64bit alpha version from http://labs.adobe.com/technologies/flashplayer10/ then you need only 64bit version). Then restart firefox (and you can check with mozilla-plugin-config -l that the plugin got installed correctly).

In case flash plugin crashes now, the only thing would be that you get a grey rectangle in place where the plugin should be shown. Reload the page and off you go.
