Global objects construction and destruction

In object-oriented programming (OOP), global objects are considered harmful. Particularly in C++, there's even more reason to think twice before using them: a global object construction occurs before a program's outset, so any exception thrown from its constructor can never be caught. This is also true for a global object's destructor throwing an exception: the destruction of a global object takes place conceptually after a program's termination so this exception can never be caught either.
