"If an object of static storage duration has initialization or a |
15 |
destructor with side effects, it shall not be eliminated even if |
16 |
it appears to be unused, except that a class object or its copy |
17 |
may be eliminated as specified in 12.8." |

Is that related to linking? I don't think so. Still, PE and ELF are |

older than the first C++ spec so, IFF your reading of this chapter is |

correct, C++ is broken by design. |
