## Hello, i wonder why the following code does not work:
##--- copy here ---
# 1 "a.cpp"
# 1 "<built-in>"
# 1 "<command line>"
# 1 "a.cpp"
class a
{
 public:
  virtual void bb( int )
  {
  }

  void bb( const char * )
  {
  }
};

class b: public a
{
 public:
  void bb( int )
  {
  }
};

int main()
{
    b bb;
    bb.bb( "" );
    return 0;
}
