[Boost-users] Anyone see anything like this??

In mem_fn.hpp (not sure what is doing this but my bet is bind or 
function) there is a function dm<R,T>::call<U> that looks like so:

    template<class U> R const & call(U & u, void const *) const
    {
        return (get_pointer(u)->*f_);
    }

The stupid compiler (MSVC++ 8.0) complained that u is an unreferenced 
formal parameter and then crashed.  So I told it to stop giving me that 
warning in the file that is causing the issue and the problem went 
away...until I set about trying use the function that I just wrote that 
caused it.  Now I get this:

1>d:\boostvs39\include\boost\bind\mem_fn.hpp(334) : error C4716: 
'boost::_mfi::dm<void __thiscall(unsigned 
int),esi::units::unit_settings>::call<esi::pipeflo::document::unit_pool 
* const>' : must return a value

I can't recreate this in a simple program.  Here's the code of the 
function that I just wrote when this BS started happening:

  void on_change(wxGridEvent & event)
  {
    using namespace esi::units::systems::SI;
    using namespace esi::pipeflo::document;
    if (event.GetCol() == 0) return;

    std::pair< boost::function< std::vector< std::string >() >
             , boost::function< void(size_t) > > functions[] =
    {
      std::make_pair( boost::bind(&unit_settings::get_labels<pressure>, 
&units)
                    , boost::bind(&unit_settings::set_selection
<pressure>, &units) )
    , std::make_pair( boost::bind(&unit_settings::get_labels<length>, 
&units)
                    , boost::bind(&unit_settings::set_selection<length>, 
&units) )
    , std::make_pair( boost::bind(&unit_settings::get_labels<mass_flow>, 
&units)
                    , boost::bind(&unit_settings::set_selection
<mass_flow>, &units) )
    , std::make_pair( boost::bind(&unit_settings::get_labels
<dynamic_viscosity>, &units)
                    , boost::bind(&unit_settings::set_selection
<dynamic_viscosity>, &units) )
    , std::make_pair( boost::bind(&unit_settings::get_labels
<mass_density>, &units)
                    , boost::bind(&unit_settings::set_selection
<mass_density>, &units) )

    };

    std::vector< std::string > labels = functions[event.GetRow()].first
();
    std::vector< std::string >::iterator fit = std::find(labels.begin(), 
labels.end(), grid->GetCellValue(event.GetRow(), event.GetCol()));
    assert(fit != labels.end() && "Somehow the user selected a unit that 
doesn't exist.");
    if (fit != labels.end())
    {
      functions[event.GetRow()].second(std::distance(labels.begin(), 
fit));
    }
  }

The namespace esi::units::systems::SI has a "using boost::units::si" in 
it.

I am not really expecting anyone can help me but I thought I'd try 
anyway.  Surely other people have been stabbed in the face by this 
terribly buggy compiler.
