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.
