--- Comment #4 from Jason Merrill <jason at gcc dot gnu.org> ---
Reduced:
struct A { int i; };
template <class T> T g(T);
template <class U, class... Vs>
void f(U u, Vs... vs)
{
[vs...](auto x) {
(g(x) .* ... .* vs) = 42;
}(u);
}
int main()
{
f(A(), &A::i);
}
Basically, the problem is that fold-expressions don't currently support partial
instantiation like that done by tsubst_lambda_expr.
