98905 - Talkback does not catch the crash when Mozilla blows the stack

Status: RESOLVED INVALID

(Core Graveyard :: Talkback Client, defect)

Description

[André Dahlqvist]

[Build: 2001-09-04-21 on Linux]

Talkback initializes correctly for me (and I can launch talkback manually) but
when I reproduced the bug #98901 mozilla crashed without talkback catching it. 

To reproduce:

1) Get a talkback enabled build for Linux (I think this is linux-only).
2) Click on the attachment below (which is a .html file from bug #98901)

Result: Talkback should catch the crash.
Expected result: Talkback should catch the crash.

I have seen this happen before, and I even vagely remember posting a comment to
a similar bug before. I could however not find that bug when I searched for it.

Attachment: Open this .html-file in mozilla and watch talkback fail to catch the crash that occurs.

Comment 2

[André Dahlqvist]

In case I wasn't clear enough, I see that talkback is initialized on startup:

Hey : You are in QFA Startup 
(QFA)Talkback loaded Ok.

Sorry for spam, but I noticed I made a typo in my build-ID. It should be
2001-09-07-21.

Setting severity to major.

Comment 5

[André Dahlqvist]

Just to prove that talkback was not completely malfunctioning I killed mozilla
on purpose with "kill -SEGV process-id" and I was presented with a nice shiny
talkback window.

Using 2001091721/linux
When mozilla crashes on www.pointcom.com
(http://bugzilla.mozilla.org/show_bug.cgi?id=100273)
talkback does not catch the crash either.
I get:

(QFA)Talkback loaded Ok.
/home/me/TMP/mozilla-linux/mozilla/run-mozilla.sh: line 72: 20530 Segmentation
fault      $prog ${1+"$@"}

I ran into this again today with 2001-12-07-21 on Linux when running chofmann's
browser buster. After almost 400 pages mozilla "finally" crashed, and it was
very frustrating to see talkback NOT catch it.

I think a lot of valuable crash data is getting lost because of this.

The example file does not crash Mozilla 1.3 pre-beta build 2003012908, Windows
98. Does it still crash Linux Mozilla?

comment #1 attachment is missing, also missing from bug 98901.
I'll run browser buster here for a while, but this will be hard
to track down.  Any particular versions of linux we're talking about here?
I'm testing this on rh73.

[Andrew Schultz]

note that the original problem here (not catching the crash in bug 98901) is
because that crash blew the stack (see bug 98901 comment 18).  In that situation
(and a few others), talkback rarely works, but it still works for most crashes.

I don't know if it's even possible to fix something like this or not.

without the talkback source, we're not going to be able to fix talkback bugs
like this.
