[Boost-users] [iostreams] Problem with gzip_decompressor

Dear all,

  Some compressed data was stored in a vector<char> buf (don't know if it's
a right way to store compressed data). I used the "buf" as a source, and
tried to add a gzip_decompressor to restore those data. I have tried the
following approach, but it doesn't work.

  vector<char> buf;

  /* fill in the buf */

  namespace io = boost::iostreams;
  io::filtering_istream in(boost::make_iterator_range(buf));
  in.push(io::gzip_decompressor());

What I got is an exception,

  terminate called after throwing an instance of
  'boost::exception_detail::clone_impl<boost::exception_detail::error_info_injector
  <std::logic_error>>'
  what():  chain complete
  Aborted

  How can I compose a source which comes from a container, and add a
gzip_decompressor to the source? Thanks in advance.

Regards,
chenwj
