That's because there are different overloads of make_iterator_range. 
You're not supposed to specify any template parameter, since the point 
of all make_* functions is to deduce these automatically.

If you want to specify them, then use the constructor of iterator_range 
directly.

make_iterator_range(double*, double*) does return an 
iterator_range<double*>.
