--- Comment #10 from Martin Sebor <msebor at gcc dot gnu.org> ---
For the test case in comment #2 GCC 7.0 print the following errors. The
English text of the errors looks fine but the types are still pretty wacky:
$ cat t.C && /ssd/build/gcc-git-svn/gcc/xgcc -B /ssd/build/gcc-git-svn/gcc -S
-Wall -Wextra t.C
struct A { void foo(); };
struct B : A {};
typedef void (B::*B_ptr) ();
template <class T, void (T::* U)()> struct CT {};
CT<B, (B_ptr) &A::foo> c;
t.C:7:26: error: ‘void (B::*)(){((void (B::*)())A::foo), (0 + 0)}’ is not a
valid template argument for type ‘void (B::*)()’
CT<B, (B_ptr) &A::foo> c;
^
t.C:7:26: error: it must be a pointer-to-member of the form ‘&X::Y’
t.C:7:26: error: could not convert template argument ‘void (B::*)(){((void
(B::*)())A::foo), (0 + 0)}’ from ‘void (B::*)()’ to ‘void (B::*)()’
Clang 5.0 prints a much clearer error message:
t.C:7:11: error: non-type template argument is not a pointer to member constant
CT<B, (B_ptr) &A::foo> c;
^~~~~~~~~~~~~~~
