class Fun
{
public:
  int x;

  Fun() {}
};

...

void someFunc()
{
  Fun myfun();  // rather than "Fun myfun;"
  myfun.x = 12;
}

Here Derived::print() wants to call the Base::print() function as part of its implementation. Unfortunately, this doesn't call Base::print(). Base: here is treated as a label before a recursive call to Derived::print() which causes a nice happy stack overflow.

Classic. One of my favourites is:

Which will promptly tell you "left of .x must be a struct/class/union". Guess what? The empty constructor of the stack-allocated variable is treated as a forward declaration of a Fun-returning function with no arguments. This is amusing though, because adding one argument or more to the constructor will suddenly clear up the ambiguity and it will work as expected. [grin]

class c
{
public:
    c(float a,float b){ }

    void m(){ }
};

void g()
{
    int i=10,j=20;

    c v(float(i),float(j));
    v.m();
}

I actually managed to run into a kind of bug in C++ that's new to me.
