Hi, I just started testing Boost 1.34.1 and have found this piece of code produces a warning, which was not present in Boost 1.33.1: --- #include <boost/bind.hpp> struct Foo {}; struct Bar { Foo GetFoo() { return Foo(); } }; int main() { Bar bar; boost::bind(&Bar::GetFoo, bar); } --- 1>boost\boost.1.34.1\boost\boost\bind.hpp(1575) : warning C4180: qualifier applied to function type has no meaning; ignored 1> boost\boost.1.34.1\boost\boost\bind.hpp(1609) : see reference to class template instantiation 'boost::_bi::add_cref<Pm,I>' being compiled 1> with 1> [ 1> Pm=Foo (__thiscall Bar::* )(void), 1> I=1 1> ] 1> test1\test1.cpp(16) : see reference to class template instantiation 'boost::_bi::dm_result<Pm,A1>' being compiled 1> with 1> [ 1> Pm=Foo (__thiscall Bar::* )(void), 1> A1=Bar 1> ] It seems to pick this specialisation: template< class M, class T > struct add_cref< M T::*, 1 > { typedef M const & type; //bind.hpp(1575) }; When I would have thought this one more appropriate: template< class R, class T > struct add_cref< R (T::*) (), 1 > { typedef void type; // bind.hpp(1580) }; Any ideas? Thanks, Ben
