Release Notes:

Hide
The C++14 standard explicitly prohibits assigning default arguments to a
template parameter pack. However, the compile accepts such code silently, and may result in an internal error during compilation.

template <class... Types> void f(Types... args) {
    auto lm = [](Types... = args...) {};
    lm(10); // internal error here
}
int main() { f(1, 23); return 0; }
