The following crashes g++:

struct nullptr_type {

  nullptr_type ( void ) {}

  template < typename T >
  operator T* ( void ) const {
    return ( 0 );
  }

} const nullptr;

int main ( void ) {
  0 == nullptr;
}

------- Comment #1 from pinskia at gcc dot gnu dot org  2006-10-29 06:44 -------
Confirmed, we stopped ICEing sometime between 3.4.x and 4.0.0.
I am going to mark this as a regression, though I don't know if it should or
not.
The ICE has happened since at least 2.95.3.
