const char s[1] = "s";

printf (s);
return 0;
}

Thread model: posix
gcc version 4.3.0 20070731 (experimental)
[test]$ gcc-svn -std=gnu99 -Wformat=2 bar.c
bar.c: In function 'main':
bar.c:6: warning: zero-length printf format string
The format string is not zero-length, it's unterminated. The fix is simple.
I've got a patch and will send it in shortly.
