State-Changed-Why:
    the program is ill formed. you are linking ab.o into both
    the main executable and the shared library. this breaks
    the one definition rule

>Description:
The program seg faults on exit.  It certainly looks like the static class member is being destructed twice.  
>How-To-Repeat:
unzip and untar the test included.  Execute "make" at the top level.  Run the resulting "test" executable.  It will seg fault on exit.
>Fix:
If you make the static class member (static A a;) of B non-static (A a;), then the program executes successfully.  It looks like the mutiple definitions of the static member are corrupting each other.
