I think I find a bug in the GNU C++ Compiler v.2.2.2.
It occurs while a static const object was defined to be of the same class
as the one which encloses it, for example:

class X
{ public:
     static const X xo;
     // ...
}

The result is an Internal compiler error while running cc1plus.
A sample program and its compiler output are enclosed for your examination:

// test.H file --------------------------------

class X
{
  private:
    int x;
  public:
    static const X x0;
    X( int );
};

class Y
{
  private:
    X xx;
  public:
    Y();
}
    
// test.C file --------------------------------

#include "test.H"

X::X( int xi )
{
    x = xi;
}

const X X::x0( 0 );

Y::Y()
{
    xx = X::x0;
}

// Compiler output --------------------------------

Please advice me what to do.
