> The program below aborts at runtime. According to lib.istream.unformatted, p20:
>     "[getline...] stores a null character (using charT()) into the next successive location
of the array."
> $ cat t.cpp && nice make t -r && ./t
> #include <cassert>
> #include <sstream>
> int main ()

>     std::istringstream strm;
>     strm.setstate (strm.failbit);
>     char s [3] = { 'x', 'y', 'z' };
>     strm.getline (s, 2);
>     assert ('\0' == s [0]);
>     assert ('y'  == s [1]);
>     assert ('z'  == s [2]);
