this startup crash signature is starting to show up with a low volume in firefox 62, probably as fallout from bug 1468612.

Hmm, looks like we're crashing when accessing the local static variables (see for example https://crash-stats.mozilla.com/report/index/48628725-1502-4ddb-bd4a-d495e0180906) when libxul is loading at startup?

I have never seen anything like this.  Aaron, Jim, sorry for the question out of nowhere, but given your experience on Windows, have you seen a similar crash by any chance?  Do you have any explanation for what's happening here?

Don't see anything in 63. Let's close this.
