There's a bug in boost/iostreams/chain.hpp which can be fixed as follows. The
fix will appear in 1.33.1. Thanks for bringing the problem to my attention.

*** chain.hpp   9 Sep 2005 18:08:40 -0000       1.14.2.4
--- chain.hpp   11 Oct 2005 16:40:24 -0000

          pimpl_->close();
      streambuf_type* buf = 0;
      std::swap(buf, list().back());
!     buf->set_auto_close(auto_close());
      buf->set_next(0);
      delete buf;
      list().pop_back();
