86750 - Mozilla crashes when window disappears while menu still open

Status: RESOLVED DUPLICATE of bug 129785

(Core :: XUL, defect, P3)

Description

[beanladen]

Seen on Mozilla 0.9.1+/Linux 2.4.x/gcc 2.95.2/XFree86 4.0.3/fvwm 2.3.28

Example: sending Mail

Send a message under loaded network conditions so that new message
window does not disappear immediately. Then open a menu on this
window while it is still open. When the window disappears with the
menu still open, Mozilla crashes.

This may be a general bug applying to any window misused in that
way, but it's not easy to verify.

No problem...
Actually it was a little one because I had to make some working testcase before.
You can try it too, just leave open menu after OKing the alert box and wait 10s.

On LInux with 2001-06-20-21 I was unable to close a window with pulled-down menu
and thus unable to reproduce the crash. It may be a bit annoying as the window
moves independently of the menu and the menu may get lost..

The bug is still there (Linux 2001062721).
Just use the testcase as described in my previous comment.

actually, this doesn't crash in current builds, win32 and linux (moot point on 
mac where open menus hog the event loop).

Verified WFM Linux 2001093021.

I'm experiencing this on solaris. Platform is a sparc running Solaris 8. 
Mozilla is build 2001122110, the latest solaris nightly.

To reproduce:

0) Open a navigator window.
1) Load a page which will close itself, such as one of the testcases.
2) Before the window closes, click somewhere to display a menu.  I've used the
"back" menu or the "bookmarks" menu for this.
3) Park your mouse on the menu so that something is highlighted. This may not
actually be necessary.
4) Wait for the window to close itself.

Expected: Window closes, menu disappears.

Actual: Window closes. Menu remains, and mouse remains the rightward-pointing
arrow that mozilla uses for menus.  Mozilla crashes.

The above "testcase for the crash" produces the crash for me, but I'll attach a
simplified file.

Attachment: window.close() on a five-second delay

Simplified version of the previous testcase.

crashes current comm. build for 01/07/2002 on linux and a 12/28 mozilla build 
on linux, but _not_ my own mozilla build on linux, nor win32 builds (this bug 
is moot on mac os 9; haven't checked os/x)

The stack trace is the same as previously attached; crash in 
nsMenuFrame::ActivateMenu() according to talkback.
