Segmentation Fault - malloc 2D array

Trying to create a map for a little game. When initialising the map with 2D arrays using malloc, the main function will run okay when the printMap function is commented out, however when trying to display the map with printMap, it returns a Segmentation fault. Totally lost at why this isn't working. Any help appreciated.

This is work for University, who insist the code is in C89 and I compile with -ansi -pedantic -Wall -Werror.

GAME.C file

#include<stdio.h>
#include<stdlib.h>
#include<time.h>
#include"random.h"

void createMap(char*** map, int xCoord, int yCoord) {
    int i, j;
    xCoord += 2;
    yCoord += 2;
    char** mapArray;

    mapArray = (char**)malloc(yCoord * sizeof(char*));
    for (i = 0; i < yCoord; i++) {
        mapArray[i] = (char*)malloc(xCoord * sizeof(char));
    }
    for (i = 0; i < yCoord; i++) {
        for (j = 0; j < xCoord; j++) {
            mapArray[i][j] = "0";
        }
    }
    *map = mapArray;
}

void printMap(char** map, int xCoord, int yCoord) {
    xCoord += 2;
    yCoord += 2;
    printf("%d, %d", xCoord, yCoord);
    int i, j;
    
    for (i = 0; i < yCoord; i++) {
        for (j = 0; j < xCoord; i++) {
            printf("%d %d", i, j);
            printf("%c", map[i][j]);
        }
        printf("\n");
    }
}

MAIN.C file

#include<stdio.h>
#include<stdlib.h>
#include<time.h>
#include "random.h"
#include "game.h"

int main(void) {
    int xCoord = 5;
    int yCoord = 5;

    char** map;

    createMap(&map, xCoord, yCoord);
    
    printMap(map, xCoord, yCoord);
    return 0;
