Should g++ emit warning against the bug shown in the following program?
I am running g++-1.34.1 on a SUN3/60M OS4.0.1.

[1]: cat bug.c
class base;

class base {
private:
  base *next;
public:
  base (void);
#ifndef BUG
  void Insert (base* elem);
#else
  void Insert (base*& elem);
#endif
};

void main (void) {
  base* FOO =  new base ();
  FOO->Insert (new base());
}
