If I construct a ostrstream, with
  ostrstream os (s,sizeof(s))
do I have to clean ALL of s before I use it?
I'm getting strange results (i.e. I have to init ALL of s to 0)
with g++ 2.7.1, and 2.3.3.

So, my question is: is this a bug in g++, or am I missing something
about the string streams?


The following programme has this what I think is strange behaviour,
as it outputs in the last line not only the "hello, world", but
part of the old h's string s was inititalized to,  concatenated to it.

Thanks for any suggestions.


#include <iostream.h>
#include <strstream.h>
int main(int,char **){
  int i;
  char s[]="\000hhhhhhhhhhhhhhhhhhhhhhhhhhhh";
  cout<<"initial s:"<<s<<endl; //an empty string here.

  ostrstream os(s,sizeof(s));
  os<<"hello, world";
  cout<<s<<endl;          //outputs: hello, worldhhhhhhhhhhhhhhhhh
}
