Hi,

Here is the failing code:
<code>
void main()
{
    typedef
boost::iostreams::code_converter<boost::iostreams::file_sink,
WideCharToUtf8Cvt> my_sink;
std::wstring teststr(L"Blah blah.");
    boost::iostreams::filtering_wostream out;
    boost::iostreams::file_sink myFile("out.txt");
    out.push(my_sink(myFile));
    out << teststr;
}
</code>
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
