M$ Windows Media Player v6.4 (WMP) crashes Mozilla when embedded and interacted
with (i.e. press the play or stop button). 

Reproducible: Always
Steps to Reproduce:
1. make sure WMP v6.4 plugins (npdsplay.dll v3.0.2.625 & npwmsdrm.dll
4.1.00.3857) are in plugin folder before launching Mozilla
2. go to
http://mediaframe.yahoo.com/detect/lite/script.html?.intl=en&.done=/launch%3flid=wmv-100-s.2715070--133796,wmv-300-s.2715072--133797,rnv-100-s.2715073--133798,rnv-300-s.2715075--133799,wmv-56-s.2715100--133800,rnv-56-s.2715101--133801%26p=fifa%26c=onepane%26f=90353079%26.intl=en%26.small=1%26.close=1%26.ti=http%3a//us.i1.yimg.com/us.yimg.com/i/fifa/gen/pf/gotc_banner1.jpg%26.bi=http%3a//us.i1.yimg.com/us.yimg.com/i/fifa/gen/pf/gotc_banner2.jpg
3. it will detect your settings (OS, browser, connection speed & firewall)
4. accept settings, which will take you to the clip
5. while loading, 2 errors are reported successively in the status bar:
exception: null
Applet appObs notinited
then the browser is moved back to the previous page
6. go forward, back to the video clip page and click either the play or stop
buttons on the embedded WMP as the page is loading.
7. BLAMMO!

Actual Results:  Crash :(

Expected Results:  No crash, view a (supposedly) great football (soccer to the
usOFa types) goal.

In addition to the TB IDs, I have 2 Dr. Watson log files that I can attach. The
first one was grabbed when Mozilla crashed b/c of pressing the play button on
the embedded WMP & it listed an unknown module causing the crash. The 2nd log
was grabbed after Mozilla was crashed when pressing the stop button on the
embedded WMP & it indicated:

"Windows Media Player 2 ActiveX Control attempted to read from memory that does
not exist.  It may be using an uninitialized variable, or it may be attempting
to access memory after having freed it.

Module Name: MSDXM.OCX
Description: Windows Media Player 2 ActiveX Control
Version: 6.4.07.1112
Product: DirectShow
Manufacturer: Microsoft Corporation"

P.s. b/c of mplayer2's increased bloat with higher versions, and other reasons
not worth mentioning here, I cannot run WMP above 6.4, so please do not ask me
to install a higher version of WMP. Also, this needs to be tested on NT and
Win95, as 6.4 is the highest WMP for those 2 flavors of winblows.

The steps here give an error, then crash Netscape v4.79 build 20011017 (should
theoretically crash versions 6.x & 7.x, thought I haven't tested the higher 2
[don't have them installed]):

# Error: malloc failed while setting up zig (-1)
#           jar file: unknown
#           path: D:\PROGRAM
FILES\NETSCAPE\COMMUNICATOR\PROGRAM\\java\classes\JAVA40.JAE

hit OK to that message, and then Netscape 4.79 crashes & neither Talkback nor
Dr. Watson are triggered. :(  However, with the java error, I'm not sure 4.79 is
crashing for the same reason as Mozilla...

It works for me, using WinXP and Windows Media Player 8.0 and build 2002053106

Dlls :

npdsplay.dll : 3.0.2.627
npwmsdrm.dll : 4.0.1.3920

It seems to be a WMP 6.4 bug !

Do you tried with WMP 7.1 ?

Comment 4

[earthsound]

Frederic, as per comment #2, I will not run anything higher than 6.4.
Additionally, WinNT/95 users can't run anything higher. Yes, it seems to be a
6.4 issue, albeit a nasty one...
