        <pre>Godbolt: <a href="https://godbolt.org/z/1dMKE1W81">https://godbolt.org/z/1dMKE1W81</a>

If we compile:

  #include <stdio.h>

  int main()
  {
      printf("%p\n", nullptr);
  }

with clang++ -Wformat -pedantic, we get:

<source>:5:20: warning: format specifies type 'void *' but the argument has
type 'nullptr_t' [-Wformat-pedantic]
    printf("%p\n", nullptr);
            ~~     ^~~~~~~

I believe that's _too_ pedantic. It is well and proper to pass nullptr to a %p
without casting it.</pre>
