2642,bug constructing from a reference to another boost::function,Steven Watanabe,Douglas Gregor,"The following code throws a bad_function_call exception
because the constructor for f2 decides that since f1 is
empty, f2 ought to be empty as well.

{{{
#include <boost/function.hpp>
#include <boost/ref.hpp>

void f() {
}

int main() {
    boost::function<void()> f1;
    boost::function<void()> f2(boost::ref(f1));
    f1 = f;
    f2();
}
}}}

The attached patch fixes the problem.
