--- Comment #53 from janus at gcc dot gnu.org ---
Carrying over the test case from PR 79572:


#include <iostream>

void f(const int &iref) {
  if (&iref)
    std::cout << iref << std::endl;
  else
    std::cout << "iref is NULL" << std::endl;
}

int main () {
  f(*((int*) NULL));
  return 0;
}


This dereferences a NULL pointer in a very explicit fashion, but is not being
caught by -Wnull-dereference, neither with 6.2 nor with current 7-trunk.
