785038 - WebWorker crashes Firefox 14.0.1 (Ubuntu 10.04, Firebug 1.10.2)

Status: RESOLVED DUPLICATE of bug 775543

(Core :: JavaScript Engine, defect)

Description

[Dennis Boldt]

My System:

- Ubuntu 10.04 - 64 bit
- Firefox 14.0.1
- Firebug 1.10.2

(empty profile with Firebug)

Try this minimal working example, with the options shown (sorry, I am somehow not able to switch to the english version) in the screenshot:

Firefox crashes as soon I am clicking on the test-link. Impotant is the breakpoint. Without it, it is not crashing.

Here the crash report:

Can you provide the full stack trace (see https://developer.mozilla.org/docs/How_to_get_a_stacktrace_for_a_bug_report)?

Comment 2

Or even just the crash id from about:crashes, assuming this is a mozilla.org Firefox build?

I just rerun it and I got the crash ID: bp-7e725621-56d2-4020-bd1a-2d53e2120823

  http://crash-stats.mozilla.com/report/index/bp-7e725621-56d2-4020-bd1a-2d53e2120823

I am using this build:

  http://download.mozilla.org/?product=firefox-14.0.1&os=linux&lang=en-US

Do you need more infos?

No, that's perfect.

Looks like a null-deref when the Xray code touches the worker.  This was actually fixed just yesterday in development builds; we're going to get a fix into Firefox 16 as well, but Firefox 15 will ship without that fix, unfortunately.

[Boris Zbarsky [:bzbarsky]]

And Dennis, thank you very much for the bug report!

Comment 6

[Dennis Boldt]

Just in FF16? Means, I must downgrade or debug my Worker with Chrome. It's a pity.

P.S.: it took quite a lot of time to figure it out :)

Comment 7

[Boris Zbarsky [:bzbarsky]]

Unfortunately, yes.  Code freeze for Firefox 15 was day before yesterday.  :(

You can use Aurora 16.0, http://www.mozilla.org/firefox/aurora/, or soon Firefox 16.0 Beta, http://www.mozilla.org/firefox/beta/.

Good idea. Thanks for the hint.

FYI: in Aurora 16.0a2 (2012-08-23), this bug is still existing.

Yes because the patch hasn't yet landed in Aurora. Se bug 775543 for more.

The bug is not existing in `Aurora 17.0a2 (2012-09-06)` anymore. 

Thanks for the fix.
