[Bug c++/42356] New: confused compiler

[igodard at pacbell dot net]

This code:
template<typename T>
class   freeList {
public:
    T*      newNode() { return 0; }
    template<typename U>
    T*      newNode(U u) { return newNode()->init(u); }
    template<typename U, typename V>
    T*      newNode(U u, V v) { return newNode()->init(u, v); }
    };

class   bar {};
class   baz {};
class   foo : public freeList<bar>, public freeList<baz> { };

int main() {
    foo     f;
    bar*    b = f.newNode<bar>();
    }


gets you:
