Ah...  I didn't see it because I looked in the wrong places.

I am not so sure about this.  We all hack.  One hack vs. 
another.  I doubt if there are any nontrivial programs without 
at least a few ugly hacks.

It gives me an idea ...  Where it now prints "improper link 
order", construct it.  Instead of a map, have a pointer to map, 
use new and delete.  It is the map that needs initializing.

I am aware of one, from long ago.  The destruction order was 
exactly the construction order.  Perfectly wrong.

I am not sure, but I see a way to test it.

Thanks.  I will try it.
