Package: libc6
Version: 2.11.2-10
Severity: normal

Hi, 
As described in the subject, the ferror() function return no error even if the 
stream as been previously closed : 

Here is a simple program to test this : 

#include <stdio.h>

void main()
{
        FILE * f;
        f=fopen("test","r");
        printf("First -> %d\n",ferror(f));
        fclose(f);
        printf("Second -> %d\n",ferror(f));
        
}

with a file named "test" in the same directory as this program ( the file can 
be empty )
The execution of this program show this : 

root@debian:~# gcc -o test_ferror test_ferror.c
root@debian:~# ./test_ferror 
First -> 0
Second -> 0

The result of the second output should'nt be 1 ? 

Regards

Julien GODIN
