224075 - [ActiveX] IE crashes when loading second page containing Mozilla ActiveX control

Status: RESOLVED INCOMPLETE

(Core Graveyard :: Embedding: ActiveX Wrapper, defect)

Description

[Hannes Wallnoefer]

User-Agent:       Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.6a) Gecko/20031027 Firebird/0.7+
Build Identifier: Mozilla 1.5 ActiveX control from MozillaControl15t1.exe on Win2K

I successfully installed the standalone Mozilla ActiveX control from
http://www.iol.ie/~locka/mozilla/MozillaControl15t1.exe . When visiting
http://www.iol.ie/~locka/mozilla/mozctltest2.htm the control loads and works
fine, but when I open a second IE window with the same location, IE crashes with
the message "Microsoft Internet Explorer has encountered a problem and needs to
close. We are sorry for the inconvenience" and some further error data which I
can provide if needed. 

Reproducible: Always

Steps to Reproduce:
1. Install http://www.iol.ie/~locka/mozilla/MozillaControl15t1.exe
2. Go to http://www.iol.ie/~locka/mozilla/mozctltest2.htm
3. Open a second IE window and go to the same URL

Actual Results:  
IE crashes.


I'm using IE 6.0.2800.1106 on a pretty up-to-date Windows 2000 (Windows Update
doesn't recomand any urgent updates).

I get this bug totally repeatable on the test page at http://www.iol.ie/~locka/mozilla/mozctltest1.htm

Just try and open two pages with the Mozilla control in them. I am on XP. This is with the july 
6 2004 1.7 control.

This is an automated message, with ID "auto-resolve01".

This bug has had no comments for a long time. Statistically, we have found that
bug reports that have not been confirmed by a second user after three months are
highly unlikely to be the source of a fix to the code.

While your input is very important to us, our resources are limited and so we
are asking for your help in focussing our efforts. If you can still reproduce
this problem in the latest version of the product (see below for how to obtain a
copy) or, for feature requests, if it's not present in the latest version and
you still believe we should implement it, please visit the URL of this bug
(given at the top of this mail) and add a comment to that effect, giving more
reproduction information if you have it.

If it is not a problem any longer, you need take no action. If this bug is not
changed in any way in the next two weeks, it will be automatically resolved.
Thank you for your help in this matter.

I just went and rechecked, and the crash is still there, repeatable. 

This time I was on a relatively new XP service pack 2 install with all updates as of Sep 20 2005, and I 
downloaded and installed MozillaControl 1.77. Then I started up IE 6, went to http://www.iol.ie/~locka/
mozilla/mozctltest2.htm, which worked fine. Was able to surf where I wanted to in the control. THen 
open up a second IE window pointed at the same address, and down IE goes..

Here is the call stack. (trying to derefence a null pointer)

reporter: unfortunately we can't do much w/ a random stack trace. however if 
you can find a debug build or a build w/ symbols (or a symbol server), and can 
get a .dmp, we can see about getting useful information for it and getting it 
fixed.
