Comment(by anonymous):

 The commit mention above fixes the return value issue. Thanks for pointing
 this out!

 The problem with Microsofts istreambuf_iterator has already been discussed
 on Spirit's mailing list. So I recently added a new input policy:
 buffering_input_iterator which is buffering the last character it got from
 the underlying iterator, which allows to return a refernce from
 multi_pass' operator*() in this case as well. This new policy is now the
 default input policy when using make_multi_pass(). It's a bit less
 efficient than the input_iterator policy, but helps to overcome the
 problem you described.

 Regards Hartmut
