I'm using the current Boost library on Microsoft Visual Studio 2005.  I'm getting a 
warning on line 121 of transform_iterator.hpp, complaining "returning address of local 
variable or temporary".  The line in question is the body of this function:

     typename super_t::reference dereference() const
     { return m_f(*this->base()); }

My m_f supplied to the template is ordinary enough; it returns a value.

The exact same situation in a unit test gives no complaint!
Any idea what this is all about?
