Hello.

When parsing the following program:

It’s not a bug. You can’t do that. http://www.open-std.org/jtc1/sc22/wg21/docs/cwg_closed.html#61

Many thanks for the prompt answer and the pointer.
I thought this restriction was for instance methods only ...

Hello Richard,

I am afraid there is still something unclear to me
(I may be missing something obvious ...):

    Hello.

    When parsing the following program:
    ==============================__=====
    $ cat addrof-overloaded.cc
    struct S {
       static void foo(int);
       static void foo(double);
    } s;

    typedef void (*PF)(int);

    void test() {
       PF pf1 = s.foo; // No error.
       PF pf2 = &s.foo; // Error(?)
    }
    ==============================__=====

    the following parse error is obtained:
    ==============================__=====
    $ clang++ -fsyntax-only addrof-overloaded.cc
    addrof-overloaded.cc:10:12: error: cannot create a non-constant
    pointer to
           member function
       PF pf2 = &s.foo; // Error(?)
                ^~~~~~
    1 error generated.
    ==============================__=====

    Is this a known bug?

Why isn't clang issuing a similar diagnostics for the first line:

> PF pf1 = s.foo; // No error.

Reading 13.4 in the C++03 standard, there seems to be no distinction of whether or not the address-of operator is explicitly used (it is meant, for non-instance methods):

Hmm, I missed that part of your question. I think that is a bug; we should reject both examples.
