To use placement new it is needed to have
overloaded new/delete operators (or
overloaded globals).

With the definition bellow the code compiles on Intel:

class D : public Singleton < D >
{
protected:
    D (  )
    {
    }
    void* operator new(size_t, D* p) { return p; }
    void operator delete(void* p, D*) {}
};
