Bug description:
  Binary package hint: gcc-4.3

  While trying to compile virtual methods of a templated class, I get an
  internal compiler error: SegFault.

  When you look at the code, specifically the virtual and child method,
  there is clearly a logic issue.  That is my fault.  However,  users
  shouldn't see a segfault; a syntax error would make more sense.

  The follow code will reproduce the error.

  template <typename T>
  class Temp
  {
    int Val;
    public:
    operator T&(void)  { return Val; }

    virtual T& operator=(T a )
    {
      Val = a;
      return Val;
    }
  };

  class Int : public Temp<int>
  {
    public:
    Int& operator=(int a)
    {
      return (*this);
    }
  };

  int main() { return 1; }

    //Command line
  g++ main.cpp

  main.cpp:16: internal compiler error: Segmentation fault
