Hold on... you changed the question! :-)  If I modify my BC++ 4.52 program to 
call exit() (instead of throwing) in a2's ctor, I get the incorrect result of 
three A::~A() calls.  If I change it to call abort() in a2's ctor, I get zero 
A::~A()s.

Does the WP specify what/how dtors should be called in the case of an exit() 
or abort()?
