I see.
Did you consider copying the value instead of keeping a reference to
it? Also, what do you think about allowing the user to use one or the
other?
Sorry I made a mistake in the code that results in a misunderstanding.
The argument of the function g() should not be a reference:

  void g( boost::function<double (double)> func )
  {
    double t = /* … */;
    double d = func( t );
    // …
  }

  int main()
  {
    g( &f );
  }

Thus, it is a copy of the function object. There is no reason to keep a
reference to the boost::function here.
