crash [@ XPCWrappedNative::GetScope()] #2 crash for 3.1b1pre, but I hesitate to give it topcrash status until after 3.1b1 ships and we get better stats. Also appears in small quantity in 3.0.x builds. all are windows crashes. xref Bug 544610 - crash [@ nsXPConnect::GetPrincipal(JSObject*, int)] - which I thought might be related, until I compared the stacks. So just FYI. bp-4dbdd140-0403-4161-9c09-887e02100225 NG crash again.

at least one of js, caps, or xpconnect needs to avoid this stack overflow. of them, js does the most handling of stacks, so it seems like the best starting point.

about 4 thunderbird crashes per version per month. firefox even less.

Still the same 5 years later https://crash-stats.mozilla.com/signature/?signature=XPCWrappedNative%3A%3AGetScope&_columns=date&_columns=product&_columns=version&_columns=build_id&_columns=platform&_columns=reason&_columns=address&_sort=-date&page=1#reports The original issue seems to be largely gone, and what's left is not happening at a rate worth keeping an open bug without steps to reproduce.
