Comment (by ramey):

 I looked into this a little bit.

 Note that I made my own istream_iterator.hpp.  I don't remember why I did
 this, but it would well be that the std::istream_iterator manifested this
 problem. Basically, the standard istream iterator is a single pass
 iterator so once a character is read, it has to be passed by value as
 there is no guarantee that the original character address makes any sense.
 I guess this conflicted with my iterator stack template meta programming
 implemenation so I had to make my own version.  I can only speculate now
 as it was a long time ago.

 Note that my case is different in that I am/was using istream_iterator and
 you're using istreambuf iterator.  (This is the first time I've seen
 this).

 In any case, I think that solves the mystery.  Whether or not it addresses
 your interest I can't say but I can say I don't think it's an issue with
 the serialization library.
