[boost] [factory][bind] C2664 with MSVC 2015 & 1.63

1 Feb 2017

      Hello Boost,

I'm having this Problem: http://lists.boost.org/boost-users/2015/04/84176.php

That message already describes pretty much what I see, except that I use 1.63 and the latest 2015 VC++.

Errormessage:
D:\cpp\libraries\boost_1_63_0\boost\bind\bind.hpp:388: error: C2664: 'ListsModuleWidget *boost::factory::operator ()(void) const': cannot convert argument 1 from 'Module *' to 'Module *&'

bind.hpp code:
...
template R operator()(type<R>, F & f, A & a, long)
    {
...
...
this line        return unwrapper<F>::unwrap(f, 0)(a[base_type::a1_], a[base_type::a2_], a[base_type::a3_]);
   }
Compiler says:

..\..\..\..\cpp\libraries\boost_1_63_0\boost/bind/bind.hpp(388): error C2664: 'ListsModuleWidget *boost::factory::operator ()(void) const': cannot convert argument 1 from 'Module *' to 'Module *&'

        with
        [
            R=ListsModuleWidget *,
            F=boost::factory,
            A1=Module *,
            A2=const QString &,
            A3=const QString &,
            A4=QWidget *,
            A=boost::_bi::rrlist4
        ]
