--- Comment #3 from Jonny Grant <jg at jguk dot org> ---
A clang++ example, doing it as I expected, showing the type before automatic
promotion. I did with char, as I couldn't find a -Wformat-signedness for the
original example code in clang++
#include <stdio.h>
int main()
{
char b = 'b';
printf("%f", b);
}
#1 with x86-64 clang (trunk)
<source>:5:18: warning: format specifies type 'double' but the argument has
type 'char' [-Wformat]
printf("%f", b);
~~ ^
%c
