The behavior was different in the variadic template code and in the C++98 code. The code without variadic template support was not copying the functor object (e.g. a lambda) before calling it. However, in the variadic template section, QtPrivate::FunctorCall::call took the functor by value instead of by reference resulting in a copy. QtPrivate::FunctorCall::call is a helper function for QtPrivate::FunctionPointer::call which is only needed for variadic template expension. [ChangeLog][QtCore][QObject] If the compiler supports variadic templates, no longer copy functor connected to a signal each time the signal is emitted. Restoring the C++98 behavior.
