I am getting a segmentation fault on this code and I do not know why

This program is supposed to have a tortoise and hare race each other and print the race out for the user. It is giving me a segmentation fault and I do not know why. I even went through the whole code with a pen and paper to see if it worked and to my knowledge it should work but I am also an amateur to C++ so I do not know.

#include <iostream>
#include <stdlib.h> 
#include <ctime>
#include <iomanip>
#define RACE_LENGTH 50

void advanceTortoise(int* ptrTortoise)
{
    int torNum = rand()%10+1;
    if (torNum <= 6)
    {
        *ptrTortoise = *ptrTortoise + 1;
    }else if (torNum = 7) {
        *ptrTortoise = *ptrTortoise + 2;
    }else if (torNum = 8){
        *ptrTortoise = *ptrTortoise + 3;
    }else if (torNum > 8){
        *ptrTortoise = *ptrTortoise;
    if (*ptrTortoise > 50)
    {
        *ptrTortoise = 50;
    }
        return;
    }
}

{
    int hareNum = rand()%10+1;
    if (hareNum = 1)
    {
        *ptrHare = *ptrHare + 1;
    }else if (hareNum > 1 && hareNum <= 4){
        *ptrHare = *ptrHare + 2;
    }else if (hareNum > 4 && hareNum <= 7){
        *ptrHare = *ptrHare + 3;
    }else if (hareNum = 8){
