 A better testcase is:
 
 #include <iostream>
 namespace {
    struct S {
        S();
    };
    S::S () { std::cout << "One more call" << std::endl; }
    S local_s;
 }
 
 (you can insert anything you like in the constructor).  You can have as 
 many of these as you like in your program.
 
 One additional problem with the existing behaviour is that you get 
 "determinism" only if inode numbers and modification times don't 
 change.  This means that (a) it's not reproducible; users normally 
 can't control inode numbers; and (b) it's fragile, because both of 
 these can quietly vary, especially on network file systems.
