c++ - non-const reference to temporary

Hi,

this one was recently discussed on comp.lang.c++.moderated (a non-const 
reference shouldn't be allowed to be bound to a temporary):

  #include <stdio.h>

  struct A
  { };

  int f(const A &a)
  {
    printf("f(const A &)\n");
    return 0;
  }

  int f(A &a)
  {
    printf("f(A &)\n");
    return 1;
  }

  int main(int argc, char *argv[])
  {
    return f(A());
  }


But DM calls f(A &) instead of f(const A &).


bye, Christof
