error: value-initialization of reference

[David Hammarwall <david dot hammarwall at gmail dot com>]

Hi,

I've got a problem using a library where I get the compiler error
"value-initialization of reference" (using gcc4.3.2). I've isolated
the problem to the following dummy example:

int DEFAULT_OBJ = 0;

class Class_With_Ref
{
public:
  Class_With_Ref() : ref(DEFAULT_OBJ) {}
  Class_With_Ref& operator=(const Class_With_Ref &v) {return *this;}
private:
  int &ref;
};

struct Wrapper
{
  // Wrapper(){}  //Everything will work if this line is un-commented
  Class_With_Ref test;
};

int main(int argc, char **argv) {
  Wrapper t = Wrapper();
  return 1;
}

Everything will work if I explicitly declare (the empty) default
constructor in the Wrapper struct, but this is a pain considering that
there are a plethora of structs that contains a Class_With_Ref
objects. Moreover, I did not have this issue with gcc 3. Also, the
assignment, Wrapper t = Wrapper(), is implemented in the library so I
cannot change it to e.g.,

Wrapper t,t2;
t=t2;

which works perfectly in the above example.

Does anybody have any insight here?

BR,
David
