seek problem on strstream

[Benoit MAIRE <Benoit dot M at dalim dot com>]

With the following version of the compiler, I have a strange result.
gcc version 2.96 20000731 (Red Hat Linux 7.3 2.96-112)

It seems that seekp give a bad result after a write in this case. All 
works fine up to byte number 3101.
Result given is :
0
4

I hopped a result of
0
0

The same code works fine on SGI with SGI compilers. It also work on 
linux with gcc3.
Is there a known limitation of strstream or a bad usage in this code or 
is it a library bug ?

#include <strstream.h>
#include <iostream.h>
#include <string.h>

int main( int, char** )
{
 strstream s;
 char buff[3429];
 memset( buff, 'A', sizeof buff );
 char tmp[10];
 memset( tmp, 'B', sizeof tmp );

 s.write( buff, 3429 );
 s.seekp( 0 );
 s.write( tmp, 10 );  // This write makes the stream to fail for a seek 
after byte 3102

 s.seekp( 3101 );
 cout << s.fail() << endl;
 s.seekp( 3102 );
 cout << s.fail() << endl;

 return 0;
}
