112194 - [RR]Crash with R6025 - Pure Virtual Function Call

Status: RESOLVED WORKSFORME

(Core :: CSS Parsing and Computation, defect)

Description

[Stephen W. Cote]

From Bugzilla Helper:
User-Agent: Mozilla/4.0 (compatible; MSIE 6.0; Windows NT 5.0)
BuildID:    2001112009

When minimizing a DHTML-based window, Mozilla 0.9.6 crashes with the following 
error: "R6025 - Pure Virtual Function Call"


Reproducible: Always
Steps to Reproduce:
1. Open the demonstration URL
2. Click the minimize button on one of the DHTML windows (not the browser 
window)


Actual Results:  The browser raises the following alert:

Title: Microsoft Visual C++ Runtime Library.
[ program path]/mozilla.exe
R6025 - Pure Virtual Function Call

Expected Results:  Not crashed, or raised a JavaScript exception.

The crash occurs in mozilla.exe.

I've tried various combinations to identify the source of the crash, but 
haven't been able to spend much time on it yet.  

The following URL includes more basic examples derived from the same script as 
the demonstration URL.

http://www.geocities.com/wranlon/htmlstore/mdiExamples.html

The unobfuscated javascript is available at:

http://www.geocities.com/wranlon/code/mdi.template.js

Specifically, the error seems to happen when a) the gridLayout feature is 
enabled, and b) the DHTML windows are animated.

Within the unobfuscated script, circa line 3400, is the function that handles 
the minimize event, and ultimately, leads to the crash (look for: 
CMDILayoutManager.prototype._handle_layout_events).

Attachment: WinNT stack trace

Comment 3

[Phil Schwartau]

The stack trace above is from a debug trunk build 2001-11-26.
Based on this, I'm not sure this really is a dup of bug 107367.

Reopening bug -

Based on stack trace attached above, reassigning to Style System
for further analysis. Don't think it's JS Engine at fault here -

[Ian Tommins ('thelem')]

I'm getting the same error on *startup*, using build 2002010409 (after 
upgrading from one a couple of weeks older)

I have tried uninstalling and reinstalling, deleting mozver.dat and 
registry.dat but it hasn't made any difference. Running Win2000.

ALSO on Win98se (4.10.2222), Mozilla 2002-01-13-03

Occurs in Mail-News Search Messages if there are many hits - because I "OR"d
when I should've "AND"d.

Why is this Windows-only?  These pages seem fine on Linux.  I can't do much to
debug this.

In a current Windows debug build (which I now have access to), I can minimize
the windows in
http://www.geocities.com/wranlon/reference/mdi_templates/sample_template_grid.html
.  Is that what I'm supposed to do to reproduce the bug?  Does anyone else still
see this crash?

Comment 11

[Stephen W. Cote]

I haven't seen this error in the RC or 1.0 builds. From my perspective as the 
reporter, I can no longer reproduce the crash.

The following is an updated example of the same code base sans Geocities 
advertisements.  Click the HTML INPUT button to obtain a window with a visible 
minimize button.  If you don't see the button when the page loads, bump the 
browser size a few pixels (render bug?).

Based on comment 11 and based on minimizing and doing some other things with the
example page in comment 11, marking worksforme.  If you see this problem in
future builds, please reopen the bug.
