C++ Misunderstandings

The gcc documentation has an extra section called "C++ Misunderstandings" telling the people who is to be blamed for the most common annoyances and surprises :-)
The items are

• static member declarations are not definitions
• name lookup, templates and accessing members of base classes
• temporaries may vanish before you expect
• copy assignment operators copy virtual bases twice

Go read it. I guess every C++ programer will once stumble over each of them.
