2993	addressof warning in VC9	Fredrik Orderud <fredrik.orderud@…>	Peter Dimov	"CONFIGURATION:
Boost 1.39, Visual studio 2008 (VC9), WARNING LEVEL 4 (most verbose).

PROBLEM:
When iterating over a std::vector<int> with BOOST_FOREACH, the compiler returns a ""warning C4512: 'boost::detail::addr_impl_ref<T>' : assignment operator could not be generated"". This warning did not appear with boost 1.38.

{{{
#pragma once
#include <vector>
#include <iostream>
#include <boost/foreach.hpp>

// Compile with warning level 4:
int main () {
	std::vector<int> list;
	// warning C4512: 'boost::detail::addr_impl_ref<T>' : assignment operator could not be generated
	BOOST_FOREACH (const int & e, list) {
		std::cout << e << std::endl;
	}
	return 0;
}
