Arduino void loop does not loop

I am trying to blink an Array of LEDs hooked up to a pin on the Arduino.

When I upload the code onto my Arduino : 

//array of pins
int allLEDPins[4] = {2, 3, 4, 5};

//the chase function
void Chaster(int* anArray) {
  for (int i = 0; i < 5; i++) {
    digitalWrite(allPins[i], HIGH);
    delay(200);
    digitalWrite(allPins[i], LOW);
    delay(200);
  }
}

//setup pins
void setup() {
  pinMode(allPins[0], OUTPUT);
  pinMode(allPins[1], OUTPUT);
  pinMode(allPins[2], OUTPUT);
  pinMode(allPins[3], OUTPUT);
}

void loop() {
  Chaster(allLEDPins);
}

The loop function does not loop. I am using an Arduino Zero in Arduino IDE 1.6.8 on my Windows 10 machine. Thank you in advance.

You are accessing an index out of range in the for loop inside the function Chaster. Note that your array allLEDPins have only 4 elements and you tried to access allLEDPins[4] while the last element is allLEDPins[3]. This causes an error during running time.

In order to fix that, replace for (int i = 0; i < 5; i++) by for (int i = 0; i < 4; i++)
