Hello good people of internet

I was studying FreeRTOS, I expect myTaskA to overflow the stack but it does not. How come?

FreeRTOSConfig.h

#define configCHECK_FOR_STACK_OVERFLOW           2

// demo 2 : allocating huge array in stack to ovf
static void app_myTaskA( void * pvParameters ) {
    uint32_t myHugeArray[APP_DEFAULT_STACK_SIZE+1];
    printf("remStack: %dn", (int)uxTaskGetStackHighWaterMark(NULL));
    uint32_t anotherU32 = 0;
    printf("remStack: %dn", (int)uxTaskGetStackHighWaterMark(NULL));

    for(size_t i = 0; i < sizeof(myHugeArray); ++i) {
        // implementing sth so compiler does not optimize out
        myHugeArray[i] = i;
        myHugeArray[i]++;
        myHugeArray[i]--;
        anotherU32++;
    }

    while(1) { // to see if task survives and prints remaining stack constantly
        int remStack = (int)uxTaskGetStackHighWaterMark(NULL);
        if (remStack) {
            printf("remStack: %dn", remStack);
        } else {
            printf("no remStackn");
        }
    }
}

Terminal Output
