Summary Intermittent JavaScript crashes in markRoots()

Reported 2011-02-09 09:57:25 PST
As of r78038 the crashes while working with heavy JavaScript in Fedex page, have returned. The twist this that it is not every single loading of a page with JavaScript, but rather every second or third, while one is working with repetitive JavaScript pages that go back and forth. One is for sure, every 4-5 min I get a crash. Cleaned cache an all as usual, but crashes return within minutes. Attached you will find one of the reports

I'm attaching a second crash report to have more data related to the problem. As I said every 5-6 min I get a new crash report so I have them plenty.

Well also r77919 is crashing with a similar problem, so the bug must have been introduced even earlier. Overall r77919 seems more stable with javascript than r78038 I'm attaching here the crash report of 77919

It sounds like you're retesting newer builds. Can you provide the steps that you're using in your testing. Perhaps I can use them to reproduce a crash and debug it.

LIke I said it is intermittent. At first it does work as supposed. It creates a label (in fedex and heavy java script). Than as I continue with the creation of more labels, say I'm at the 3rd or 4th one, all of a sudden the browser stalls, it gives me the impression as if it would be awaiting for data from the server, shows the beach ball for a short few seconds and than finally crashes. It does seem very difficult to reproduce in a different environment.

This problem appears to be resolved in r79303, but I think already r78794 had it nailed. Thanks for the efforts.
