<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>
