Problem with a simple vector manipulation! Help!

Hi. I'm using Phytec KC-161 eval board. During my project i found a a problem with vectors. So i tried to monitor the values of a simple unsigned int vector[6] after I initialize it. And i saw that the vector's elements don't take any values. The same problem with char aString[6]; manipulation. Why? What can cause this problem - the incorect settings of the project, or from hardware? I started from the project given for Phytec KC-161 (Blinky), from \Boards directory.

#include <reg161.h>
#include <stdio.h>
#include <string.h>

void setup_serial();

void main (void)  {
        unsigned int vector[6];
        unsigned int c=0,cnt=0;

        setup_serial();

        for(cnt=0; cnt<6; cnt++){
                vector[cnt] = 1;
                if(vector[cnt] != 1)
                        putchar('!');
                else
                        putchar('1');
        }

        while (1) {
        }
}

void setup_serial(){
  /* init physical memory model */
  BUSCON0 |= 0x003F;    /*; 0 Wait no Delay */

  /* initialize the serial interface     */
  P3  |= 0x0400;        /* SET PORT 3.10 OUTPUT LATCH (TXD)              */
  DP3 |= 0x0400;        /* SET PORT 3.10 DIRECTION CONTROL (TXD OUTPUT)  */
  DP3 &= 0xF7FF;        /* RESET PORT 3.11 DIRECTION CONTROL (RXD INPUT) */
  S0TIC = 0x80;         /* SET TRANSMIT INTERRUPT FLAG                   */
  S0RIC = 0x00;         /* DELETE RECEIVE INTERRUPT FLAG                 */
  S0BG  = 0x19;                 /* SET BAUDRATE TO 19200 BAUD AT 16MHZ           */
  S0CON = 0x8011;       /* SET SERIAL MODE                               */
}

Thank you.
