--- Comment #3 from Martin Sebor <msebor at gcc dot gnu.org> ---
Today's trunk of GCC 7.0 still accepts the code.  Clang rejects it as expected:

$ clang++ -S -Wall -Wextra -Wpedantic -std=c++14 t.C
t.C:3:13: error: function declared '[[noreturn]]' after its first declaration
void func [[noreturn]] ();
            ^
t.C:1:6: note: declaration missing '[[noreturn]]' attribute is here
void func ();
     ^
1 error generated.
