568405 - Crash [@ JS_CallTracer] tracking bug

Status: RESOLVED WORKSFORME

(Core :: JavaScript Engine, defect)

Description

[chris hofmann]

currently #20 topcrash on 3.6.3. about 1300 crashes per day across all releases. we have several bugs on file already, but do we need more or deeper analysis, skiplists, or other to figure out problems beyond those showing up in mochitests that are also producing random orange?

about 1/3 of the crashes happen around startup in this sample from 2010 05 25  so the start up crashes might be one block to to look at.

Correlation to startup or time of session
1349 total crashes for JS_CallTracer on 20100525-crashdata.csv
218 start up crashes inside 30 seconds of startup
493 start up crashes inside 3 minutes of startup
185 start up crashes inside 3 minutes of last crash

here are the bugs on file now.

Attachment: distribution of js_CallTracer stacks in sample from 100 reports from 2010 05 25

here is what the distribution looks like when looking at the top 6 frames on a sample of 100 reports with stack count, firefox version affected, and top 6 frames.

Comment 2

[chris hofmann]

looks like there is no bug on file for that most frequent stack that looks like

js3250.dll JS_CallTracer	
js3250.dll fun_trace	
js3250.dll js_TraceObject	
js3250.dll JS_TraceChildren	
js3250.dll fun_trace	
js3250.dll js_TraceObject

Are you sure this is the same bug? I made no mention of a crash, in fact it hasn't crashed once.

I do not know all the Tech things that are being discussed. I crashed while on You Tube. This was the bug on the crash report. How do I stop this? Since the last FF update I crash continuously on You Tube. I have done all of the suggested changes and updates that I can find and nothing is working.

We have closed all the dependencies on this bug. This signature is gone from any new version. Only one crash in 5.0.1 in the past 4 weeks. Resolving as works for me.
