Possible bug with <sstream>

[Gabriel Dos Reis <gdr at sourceware dot cygnus dot com>]

The following problem was reported on news:fr.comp.lang.c++.

Because of unfortunate build problems I'm having on solaris-2.7 I
can't tell whether the bug was corrected in current CVS source. 
Benjamin, can you infirm or confirm?

Basically tellg() isn't reporting the right position due to whatever
reasons.

Comment expliquer ce comportement étrange avec ceci:

-=-=-=-
/* g++ -Wall -O2 */

#include <iostream>
#include <fstream>

using namespace std ;

int main( void )
{
    /* /dev/zero est un fichier de taille infinie ne contenant
       que des zeros. (Le pbl est aussi reproductible avec n'importe
       quel autre fichier) */
    ifstream file( "/dev/zero" ) ;
    cout << hex << file.tellg() << endl ;
    cout << hex << file.tellg() << endl ;
    file.seekg( 10 , ifstream::cur ) ;
    cout << hex << file.tellg() << endl ;
    file.seekg( 10 , ifstream::cur ) ;
    cout << hex << file.tellg() << endl ;
    cout << hex << file.tellg() << endl ;
}
