971225-egcs and virtual inheritance : ill implemented feature?

[Max Lawson]

	Hi, 

I'm trying to use virtual inheritance on my i586-pc-linux-glibc1 box.
But the compilation abort cause the compiler is referring to a missing 
default-ctor. 

The testcase below shows the problem. 

The workaround would be to define the default-ctor. But I would like to 
avoid it :-(


Regards, Max


P.S. Is it easy to use the CVS system ? 



// banane:$ g++ z.cc 
// z.cc: In method `xxx::xxx(double)':
// z.cc:48: no matching function for call to `x00::x00 ()'
// z.cc:21: candidates are: x00::x00(const x00 &)
// z.cc:11:                 x00::x00(double)


class x00
{
public:

  x00(double x) : x_(x) { }

  virtual ~x00() { }

  double val() const { return x_; }

protected: 

  double x_;

};

class x01
{
public:

  x01( ) { }
  virtual ~x01() { }

  virtual void f() =0;
};


class x02 : public virtual x00, public x01
{
public:

  x02(double x) : x00(x) { }

  virtual ~x02() { }
};


class xxx : public x02
{
public:

  xxx(double x) : x02(x) { }
  ~xxx() { }


  void f( ) { }

};


xxx X(1);

int main( ) { }
