Yeah, looks like maybe the callstack was corrupted. If you could build your own mozjs185-1.0.dll from source, you'd have the debug symbols and could maybe get more helpful details.

I know Deuce has been working on a major update to sbbs to use a modern JS library, so worst case, you could just wait till that lands in the master branch and this problem probably likely goes away (to be replaced by new ones). :-)
