[Bug c++/41568] New: ADL being kinky

["c2841847 at tyldd dot com" <gcc-bugzilla at gcc dot gnu dot org>]

Consider

#include <list>
//...
std::list<int> i,i2;
swap(move(i),move(i2));

This code should compile fine. Unfortunately it does not compile on gcc 4.4.1.
Error message:

std::allocator<int> >, std::list<int, std::allocator<int> >)'
