[Bug c++/28459] New: bogus diagnostic / format ‘%p’ expects type ‘void*’, but argument has type ‘void (x::*)()’

[pluto at agmk dot net]

#include <cstdio>
struct x
{
        typedef void (x::*fn_ptr)();
        void foo() { }
};
int main()
{
        x obj;
        x::fn_ptr f = &x::foo;
        std::printf( "&obj = %p, f = %p\n", &obj, f );
        return 0;
}

memb_fn.cpp: In function &#8216;int main()&#8217;:
memb_fn.cpp:11: warning: format &#8216;%p&#8217; expects type
&#8216;void*&#8217;, but argument 3 has type &#8216;void (x::*)()&#8217;

pointer to member needs a context of course but it's in fact
a pointer to method code, so casting to void* is imho acceptable.
