Item 20 - use of library functions

Consider the following program:

#include <stdio.h>

 int main (void)
        {
        printf ("%d\n", 42.0);
        return 0;
        }

This program clearly should have undefined behavior, but I can find no wording which states so.

or a type (after promotion) not expected by a function with variable number of arguments
