The following code prints "const, not const, ".
The correct result should be "not const, not const, ".

#include <iostream>
struct B {
        void a()        { std::cout << "not const, "; }
        void a() const  { std::cout << "const, "; }
};
struct D1 : private B { D1() { a(); } using B::a; };
struct D2 : private B { D2() { a(); } };
int main() { D1 d1; D2 d2; }

A wrong argument type for "new" in a class/struct like

struct Bogus { void* operator new(char); };

causes an ICE:

NewBug.cpp:1: `operator new' takes type `size_t' as first parameter
