--- Comment #1 from Manuel López-Ibáñez <manu at gcc dot gnu.org> ---
This works for me with all versions I have tried starting with GCC 6.1 (only in
C). In GCC 8.1:

<source>:13:11: error: format '%s' expects argument of type 'char *', but
argument 2 has type 'int' [-Werror=format=]
 str_fmt("%s %zu %s %s", d, str, str, d);
          ~^             ~
          %d
<source>:13:15: error: format '%zu' expects argument of type 'size_t', but
argument 3 has type 'const char *' [-Werror=format=]
 str_fmt("%s %zu %s %s", d, str, str, d);
             ~~^            ~~~
             %s
<source>:13:21: error: format '%s' expects argument of type 'char *', but
argument 5 has type 'int' [-Werror=format=]
 str_fmt("%s %zu %s %s", d, str, str, d);
                    ~^                ~
                    %d

It doesn't work in C++.
