addressof warning in VC9

[Fredrik Orderud <fredrik.orderud@…>]

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;
}

patch to eliminate noisy warning on VC++

[Eric Niebler]

This warning is actually coming from addressof.hpp, so I'm reassigning and attaching a very simple patch. Peter, I can commit this if you approve.

[Peter Dimov]

Yes, please commit and merge to release.

It seems sensible to declare hidden private copy constructor as well

addr_impl_ref(const addr_impl_ref &);
