Some crashes with a similar signature started in Beta 5: https://crash-stats.mozilla.com/report/list?signature=__delayLoadHelper2+|+xul.dll%400x2e3f60+|+nsLayoutStatics%3A%3AInitialize%28%29

It's probably related to an extension, but it happens too soon to have installed extensions in crash reports.

delayhlp.cpp is not our code.  Is it system code, or some binary extension?

It's the compiler support code for delay-loading DLLs.

Seems like this is happening while we're loading our audio components?

We stopped delayloading gkmedias in bug 740919 (which is in mozilla 14) so unless we're going to chemspill for this there's probably nothing to do here.

I couldn't reproduce this issue in Firefox 13b6. 
Marcia, could you please provide some extra STR? Maybe, some links that were opened in the moment of the crash? I've restarted the browser with several websites opened in different tabs (youtube, metacafe, vimeo, some random radio stations) and it works for me. I encountered the same behavior with the latest beta (FF 19b1), no crash seen.

This bug was filed from crash-stats - I never was able to reproduce the issue.

Thanks Marcia for your reply. Could anyone please give me some links that were opened in the moment of the crash?

I don't see crashes with these two crash signatures in recent builds.
Let's close it as workforme.
