2894,Incorrect type for buffer_size and pback_size parameters,gareth.sylvester-bradley@…,Jonathan Turkanis,"Documentation for [http://www.boost.org/doc/libs/1_38_0/libs/iostreams/doc/index.html?page=http%3A//www.boost.org/doc/libs/1_38_0/libs/iostreams/doc/guide/generic_streams.html%23stream_open stream::open] says:

{{{
    void open( const T& t,
               std::streamsize buffer_size, 
               std::streamsize pback_size );
}}}

That seems right to me.

However, on some environments (64-bit), passing std::streamsize arguments causes compilation failure, since the actual implementation has these parameters as int everywhere [*], and the template forwarding stream constructor/open don't work correctly.

Explicitly casting arguments to int in client code works, but changing these parameters everywhere in Boost.Iostreams to std::streamsize fixes things for me.

[*] E.g. at line 16 of [https://svn.boost.org/trac/boost/browser/trunk/boost/iostreams/detail/push_params.hpp boost/iostreams/detail/push_params.hpp]:

{{{
    , int buffer_size = -1 , int pback_size = -1 \
}}}
