Bug description

Here's a uuencoded compressed tar file illustrating a bug with libraries.

There is an executable D which uses libraries B and C. B and C each
use A. A winds up being initialized twice, which in the real
application leads to failure. It is not clear to me how to avoid this
problem unless I give up on structuring my code as multiple
libraries.
