Making a strcpy honeypot doesn’t sound like a bad idea…

  void nobody_calls_me(const char *stuff) {
          char *a, *b;
          const size_t c = 1024;

          a = calloc(c);
          if (!a) return;
          b = malloc(c);
          if (!b) {
                  free(a);
                  return;
          }
          strncpy(a, stuff, c - 1);
          strcpy(b, a);
          strcpy(a, b);
          free(a);
          free(b);
  }

That got those Core SDI abo vibes.
