It also accepts this code without complaints, which is another error:

template<int i>
bool test()
{
  if (bool value = this_identifier_has_not_been_declared( []() {} ))
    return value;

  __builtin_abort();

  return false;
}

int main()
{
  test<0>();
}

The wrong-code problem occurs also with this code:

template<int i>
bool test()
{
  if (bool value = []() { return 1; } )
    return value;

  __builtin_abort();

  return false;
}

int main()
{
  test<0>();
}
