/*

The following is a bug in gcc-2.3.1 which appears on both Sparc and 
SGI-IRIX4 platforms.  Getting rid of #pragma interface steps around
the problem, as will getting rid of the destructor declarations in
A & B, or the constructor definition in Base.

*/

#pragma interface

template <class T>
class Base { 
    T a;
  public:
    Base() {};
};

template <class T>
class Contains {
    Base<T> a;
};


class A {
  public:
    ~A();
};

class B {
  public:
    ~B();
};



class D: public Contains<A> {};
class E: public Contains<B> {};
