 Yes, I am aware that it is deprecated.  However, it is still used in quite a
 lot of places.
 Eventually, I will replace it with strinstream.  But during this
 'transition' period I still need to use it.
 I will try your patch.

     So it does....
 
     strstream.cc: 69 has
 
     strstreambuf::strstreambuf(streamsize initial_capacity)
       : _Base(),
         _M_alloc_fun(0), _M_free_fun(0),
         _M_dynamic(true), _M_frozen(false), _M_constant(false)
     {
       streamsize n = max(initial_capacity, streamsize(16));
 
       char* buf = _M_alloc(n);
       if (buf) {
         setp(buf, buf + n);
         setg(buf, buf, buf);
       }
 
     Wow.
 
     Are you aware that this class has been deprecated by std::stringstream?
 You might consider using it instead.
 
     However, it turns out that the bug is pretty easy to fix. You might try
 this, and let me know how it goes.
