Description of problem:
Valgrind reports error in c++ stream library if run against any c++ program that uses iostream

Version-Release number of selected component (if applicable):
3.5.0-20.fc14

How reproducible:
Every time

Steps to Reproduce:
create main.cpp:

#include <iostream> 
using namespace std; 
int main() 
{ 
  cout << "Hello, world!\n"; 
  return 0; 
}

compile like this:
g++ main.cpp -o main

valgrind like this:
valgrind ./main
