Ensure that the debug context has an Environment assigned in case a fatal error is raised. The fatal exception handler in node.cc is not equipped to deal with contexts that don't have one and can't easily be taught that due to a deficiency in the V8 API: there is no way for the embedder to tell if the data index is in use.
