--- Comment #1 from Eric Gallager <egallager at gcc dot gnu.org> ---
Testcase needs:

#include <initializer_list>

or else it errors with:

$ /usr/local/bin/g++ -c -Wall -Wextra -pedantic 67445.cc
67445.cc:1:6: error: ‘initializer_list’ in namespace ‘std’ does not name a
template type
 std::initializer_list<int> f() {
      ^~~~~~~~~~~~~~~~
$

but after adding that include, I can confirm that there are no warnings for the
example.
