Compared to Q_GLOBAL_STATIC, and assuming that MyType is a class or struct that has a constructor, a destructor, or is otherwise non-POD, the above has the following drawbacks: it requires load-time initialization of MyType (that is, the default constructor for MyType is called when the library or application is loaded); As you said, if some of these destructors touch already destroyed objects, your program could crash.

(It's my own thing, not an exercise from the book.) Answer (1 of 3): Sometimes you must create an empty destructor of a class. It could be better if I would have done a std::string(base62, sizeof(base62)/sizeof(base62[0])) instead, though. Answer (1 of 3): You may declare the destructor of a base class as pure virtual in the class declaration (as in a header or .h ), but you MUST provide a body for the base class destructor in the class definition (source or .cpp). Square brackets next to our call manager cdr analysis reporting link to act as soon be purged after a spreadsheet. If a static or thread-local (since C++11) variable is constant-initialized (see below), constant initialization is performed instead of zero initialization before all other initializations..
