After compilation, I get this output (watch the memory addresses):

0xbfc8f994::operator()(): 1

0xbfc8f990::operator()(): 2

0xbfc8f984::operator()(): 1

0xbfc8f984::operator()(): 2

I really don't know what happened (even if I can imagine).

But references are just lost and this is not good.

So, here is my question: How can I make this working ?

The arguments of call_something are passed by value.
Try:
template<class ...classes>
boost::function0<void> call_something(classes&... c)
