the example in [stream.iterators] 24.6
refers to

   partial_sum_copy(istream_iterator<double, char>(cin),
     istream_iterator<double, char>(),
     ostream_iterator<double, char>(cout, "\n"));

the function partial_sum_copy is non-existent but named "partial_sum" instead. It would even be better if such an example would use the new initializer syntax :-)

   partial_sum(istream_iterator<double, char>(cin),
     istream_iterator<double, char>(),
     ostream_iterator<double, char>(cout, "\n"));

or better

   partial_sum(istream_iterator<double, char>{cin},
     istream_iterator<double, char>{},
     ostream_iterator<double, char>{cout, "\n"});

P.S.: This has already been reported to comp.lang.c++ in 2005 but didn't seem to have taken up attention by somebody yet
http://groups.google.com/group/comp.std.c++/browse_thread/thread/cdd1d6f37f42a33c?pli=1

and it has been sitting there since Stepanov 1995
