Expanding a lambda for each parameter of a parameter pack: Clang vs. GCC

This code works fine in Clang 3.5:

#include <iostream>
#include <string>

void callFuncs() {}

template<typename Func, typename ...Funcs>
void callFuncs(const Func &func, const Funcs &...funcs)
{
    func();
    callFuncs(funcs...);
}

template<typename ...Types>
void callPrintFuncs()
{
    callFuncs(([] { std::cout << Types() << std::endl; })...);
}

int main()
{
    callPrintFuncs<int, float, double, std::string>();
}

However, in GCC 4.9, I get the following error instead:

test.cpp: In lambda function:
test.cpp:16:54: error: parameter packs not expanded with '...':
     callFuncs(([] { std::cout << Types() << std::endl; })...);
                                                      ^
test.cpp:16:54: note:         'Types'
test.cpp: In function 'void callPrintFuncs()':
test.cpp:16:58: error: expansion pattern '<lambda>' contains no argument packs
     callFuncs(([] { std::cout << Types() << std::endl; })...);

So, which compiler has a bug, Clang or GCC? The Clang behavior makes the most sense to me at least.
