bug(?): garbage produced by archive_node.get_string

[Pearu Peterson]

Hi,     
        
I finally tracked down what caused this garbage.
It was due to
        void numeric::archive(archive_node &n) const
in numeric.cpp where a fixed size buffer is defined if HAVE_SSTREAM is
undefined. If I made the following changes 

$ diff numeric.cpp numeric.cpp.orig
307c307,308
<       std::ostrstream s;
---
>       char buf[1024];
>       std::ostrstream s(buf, 1024);
329c330,332
<       n.add_string("number", s.str());
---
>       s << ends;
>       std::string str(buf);
>       n.add_string("number", str);

then the garbage disappered.

So, why you define fixed size buffer if ostrstream has the same
functionality as ostringstream (at least in gcc system)?
