Does BOOST_NO_CXX11_RVALUE_REFERENCES is defined ?
I managed to make it work defining it, but when it is not defined then the code goes to line 917 of bind.hpp; and it does not work because of the list_add_cref function which cast the reference in a const one.

Using VS2013 and yes the code I gave is only a non-working sample code to expose the problem.
Working with VS2013 on boost 1.58.0 release.

The code still compiles for me; VS2013, boost- 1.58.0.

results in error C2664: cannot convert from 'const std::vector<int*> &' to 'std::vector<int*> &'

This code (after #include <vector> and A:f -> A::f) works for me under VS2013 and the current develop branch. What compiler are you using?
