#8437: /boost/iostreams/stream.hpp possibly wrong detail::stream_base superclass

 Reporter:  anonymous  |        Type:  Bugs            
   Status:  new        |   Milestone:  To Be Determined
Component:  None       |     Version:  Boost 1.52.0    
 Severity:  Problem    |    Keywords:                  
-----------------------+----------------------------------------------------
 The file contains:

 typedef typename stream_traits<Device, Tr>::stream_type stream_type;
 ...
 stream_base() : pbase_type(), stream_type(&member) { }

 Thus stream_type *must* be a supertype of stream_base; however,
 the only supertypes are:

     : protected base_from_member< stream_buffer<Device, Tr, Alloc> >,
       public Base

 And the default value for template argument, Base, is:

           typename Base = // VC6 Workaround.
               BOOST_DEDUCED_TYPENAME
               detail::stream_traits<Device, Tr>::stream_type

 So I would guess type stream_type typedef should be removed
 and Base substituted for stream_type in the CTOR intialization list.
