Just to be clear: lexical variables don't suffer from this problem, even lexical variables at file scope. That implies that lexicals are destroyed before global destruction begins (which I believe to be true but I haven't verified that beyond testing that lexicals don't suffer from this problem).

To be extra clear: destroying a lexical variable won't necessarilly destroy the object that it references. If you have other references to that same object and any of those reference manage to survive until global destruction, then your object will survive until then as well (and can so could then suffer from misordered destructions).
