This is an unfortunate compiler bug. You can force the instantiation of the 
function by using

    typedef std::vector<uint32_t> V;
    void (V::*pm)( uint32_t const& ) = &V::push_back;

    boost::bind( pm, ... );

but it's somewhat clumsy. I know of no other fix apart from upgrading your 
compiler.
