But what about the following? namespace foo { char const* str = "hey"; struct A { A() { cout << str; } } obj; } Is this still undefined behavior, or is there a special provision for pointers initialized with string literals?

When I use static variables in C++, I often end up wanting to initialize one variable passing another to its constructor. In other words, I want to create static instances that depend on each other. Within a single .cpp or .h file this is not a problem: the instances will be created in the order they are declared. However, when you wan...
