--- Comment #9 from Jonathan Wakely <redi at gcc dot gnu.org> ---
Although that change just makes a latent bug apparent, this doesn't use
std::function and still fails the same way:

extern "C" int printf(const char*, ...);

int main()
{
  static int a;
  void(*f)(int) = [](auto) { printf("%d\n", a); };
  a = 1;
  f(0);
}

This has always failed, so isn't a regression, but for some reason the library
change in r232274 now hits this bug.
