            Bug ID: 60959
           Summary: Does âcout<<(char*)NULLâ doing âclose(1)â ?
           Product: gcc
           Version: unknown
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: c++
          Assignee: unassigned at gcc dot gnu.org
          Reporter: sree.gooogle at gmail dot com

In the following piece of C++ code I have used cout<<(char*)NULL; after this
line, my program printing nothing to the output screen. Does it mean I have
done close(1) with cout here?

#include<iostream>
using namespace std;

void f(){
    cout<<"\nfun\n";
}

main(){
cout<<(char*)NULL;
f(); //not getting printed !
cout<<"\nhello\n";  //not getting printed !
cout<<"hii how are you?"; //not getting printed, why??
}

compiled using:
g++ myprog.cpp
run:
./a.out

o/p:
 Prints nothing

I have tried this code in gcc as well as DevCpp compiler, same behavior
observed. Is this a compiler bug? Please provide detailed information about
this behavior. 

Thank you!
