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 m
ore helpful details.
I know Deuce has been working on a major update to sbbs to use a modern JS libra
ry, 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). :-)
