Done. I adapted and further reduced a mini-std::function available in
g++.dg/cpp0x/variadic-function.C

This is fixed in trunk, it would be nice to commit a compact testcase.

ICEs from GCC 5.1.0 on all releases (including current trunk).

This is a bit reduced test-case:

#include 
struct A {};
template  struct typelist {};
template  std::unique_ptr chooseB(typelist);
template 
std::unique_ptr chooseB(typelist choices, Idx, Rest... rest) {
  auto f = [=](auto) { return [=] { return chooseB(choices, rest...); }; };
  std::function fs[]{f(Cs{})...};
}
main() { chooseB(typelist{}, 0, 1, 2); }
