So I think > enlarging before running the debugger sounds like the right solution. Yes, assuming we can make sure the debugger itself does not try to traverse a circular structure. Also, we should disallow recursive re-entering the debugger in this case. But perhaps there are already facilities for that, I don't really know this area all that well.
