--- Comment #1 from Paolo Carlini <paolo.carlini at oracle dot com> 2011-11-22 15:37:17 UTC ---
Can be reduced to this, and seems a Regression:

struct Funny
{
  int print3(int) const;
};

template<typename X, X ff>
void c();

template<typename X, X ff, typename R, typename... A>
void xx(A... args)
{
  c<decltype(ff), ff>();
}

int main()
{
  xx<int (Funny::*)(int) const, &Funny::print3, int, int>(3);
}
