Go to this page. Works with an 8/3 nightly, broken with this patch (paper isn't rendered).

Hopefully this is bug 677743, a PIC bug which is really easy to manifest when using typed arrays that are at varying byteOffsets into array buffers.  I saw this yesterday when merging to TI and will be pushing to inbound shortly.

Andreas, I don't think the release drivers are the right team to be tracking or driving this. Probably better to get JS folks digging in to this. Or do you think that there's a Firefox release impact here for Firefox 7 or 8?
The patch broke typed arrays, are very frequently used web feature. The patch has to be backed out or the bug fixed before we release.
I'm testing the fix for bug 677743 as we speak.
Confirmed that bug 677743 fixes pdf.js.

Andreas, thanks for the explanation. That's precisely the data I was missing that we needed to understand the tracking request.
Sure, thanks for triaging :)
