From Bugzilla Helper:
User-Agent: Mozilla/4.76 [en] (X11; U; Linux 2.2.17 i686)
BuildID: 2001022705/2001022711
[I had to fall back to Netscape 4.76 to submit this bug report!]
Several times in a row now, I've attempted to submit new bug reports using the
Bugzilla Helper page, and each time, the browser has crashed with a SEGV after
clicking on the "Open Bugzilla Entry Form" button.
Reproducible: Always
Steps to Reproduce:
1. Fill out a bug report in Bugzilla Helper.
2. Attempt to open the Bugzilla Entry form to submit the bug report.
Actual Results: The browser crashes with a SEGV.
Expected Results: The entry form should come up.
On the most recent occasion, I ran under "./mozilla -g" to capture a backtrace
of the crash, which follows:
Program received signal SIGSEGV, Segmentation fault.

This may not always be reproducible. I just tried a minimal bug report (just
enough to pass the pre-submission tests) and the entry form DID come up without
crashing. I had 2-3 crashes in a row that were real bug reports, which have now
been lost. (I'll have to attempt to file those lost reports again with NN4.)

I'm guessing at a common theme here: Security is checking to see if a page
calling a function has the right to do so. This can be triggered by an
event, as we see in the call stack reported above. Note that the stack
frames pass through libcaps.so just before we crash -
I took a quick look through TalkBack reports with JS_GetFunctionObject
as the signature. For example, here is one for NN6.5 from 2001-02-27:
http://cyclone/reports/incidenttemplate.CFM?reportID=124&style=0&tc=92&cp=1&ck1=

Mitch explained this possibility to me, and he will take a look at it.
Also cc'ing Brendan, in case he feels a JS Engine issue may be involved -

Just found out from jpatel that this is currently our #1 topcrasher:
Crash Analysis from Seamonkey Trunk builds since 2001021800
Look here for bugs ready filed on these crashes:
http://bugzilla.mozilla.org/buglist.cgi?keywords=topcrash&order=bugs.bug_id
Look here for Details crash data as web page
http://www.mozilla.org/projects/seamonkey/reports/ns6analysis.html
Total blackboxes in this sample: 1010
Total unique users: 352
MTBF For these builds is estimated at 2.983113 hours,
based on 974 reports and 2905.552222 hours of user testing
from testers that have crashed and reported problems.
(dev. builds tend to have low MTBF)

Could this be a dup of joki's bug 31847? What's the source that adds the event
listener or sets the event handler that's firing?
/be
Doubt it's a dup of 31847. Looks more like recent regression.
On linux 2001022721 i crash each time i double-click a link in sidebar history.

I mean by dup of 31847 that this bug is another manifestation of the underlying
failure to root the event handler. It may be a new symptom; it may be exposed
due to some more recent change that acted as an "agent cause", but the root
cause is likely to be the same as the one reported in bug 31847.

Seeing this on Windows 98/2000 as well Heres the info:
Steps to reproduce:
1) Close and restart Mozilla (important wont work otherwise)
2) go to www.tweakers.net
3) Click a link under the "Tech Forums" section

Brendan, could I get your help in debugging this? Seems to be happening a lot,
but most often through caps. Is there a bad call in caps that's causing this, or
do you think it's a problem in the engine?

Comment 13•24 years ago

I keep pointing to bug 31847, and I mean it. This is not an engine bug. It's
not a bug in mstoltz's code on the stack just below JS_GetFunctionObject, I bet.
It very likely arose due to a source code change in the XUL/JS that define and
add the handler, which would be implicated deeper on the stack.
The latest stack shows an onload handler being fired, I think. What is the URI
of the document loaded in that docshell? What is its onload handler or load
event listener?

Despite the fact that this is out top crasher, I can't seem to reproduce it on
either Windows or Linux in this morning's build. Any clue as to what I'm
missing? Does it only happen in optimized builds, or only with certain skins?
Let's try to narrow down the conditions under which this crash occurs.

I can repro this consistently with the steps at bug 71092 (if that's a
duplicate). Just hit Ctrl N about 5 times pretty quickly and it should crash
for you

currently the #3 crasher on the Trunk. Here are some user comments and urls to

Brendan, this doesn't look like a dup of 31877 to me. 31847 is crashing in
js_LockScope1, and this one's crashing in js_GetFunctionObject. Do you still
think they have the same cause?

Never judge a crash by the victim frame at the top of the stack.
Yes, I still think this is a dup of 31847, which can crash the JS engine in many
places, by passing in a dead (garbage-collected, possibly even recycled as
another JS gc-thing, or even via the malloc heap) function object.

Giving the JSDOMEventListener a strong (rooted) reference to the event handler
function object stops the crash from happening, but it might leak.

So this is a dup of 31847. I'll attach a revised patch there and leave it to
joki to bless it and check it in.
