尝试克隆函数时出现分段错误（在C中）

我正在尝试使conway成为生活的游戏，当我将其单线程运行时，它可以完美运行，但是如果我尝试使用clone（）使其运行，则会导致分段错误。如果可能的话，有人可以帮助我找出原因吗？

主要的

int main(int argc, char *argv[])
{
    const int STACK_SIZE=65536;
    int checkInit=0;
    int i;
    int j;
    int *stack;
    int *stackTop;
    FILE *file1;
    int numThreads;

    if(argc != 3) {
        fprintf(stderr, "Usage: %s <Executable> <Input file> <Threads>\n", argv[0]);
        exit(1);
    }

    file1=fopen(argv[1],"r");
    if(file1==NULL) { //check to see if file exists
        fprintf(stderr, "Cannot open %s\n", argv[1]);
        exit(1);
    }

    fscanf(file1,"%d",&N);

    stack=malloc(STACK_SIZE);
    if(stack==NULL) {
        perror("malloc");
        exit(1);
    }
    stackTop=stack+STACK_SIZE;

    numThreads=atoi(argv[2]);
    calcPerThread=N/numThreads;
    eCalcPerThread=calcPerThread;

    B = malloc(N * sizeof(int *));
    A = malloc(N * sizeof(int *));
    for (i = 0; i < N; i++) {
        A[i] = malloc(N * sizeof(int));
        B[i] = malloc(N * sizeof(int));
    }

    system("clear");
    for(i=0; i<N+2; i++)
        printf("-");
    printf("\n");
    for (i=0; i<N; i++) {
        printf("|");
        for(j=0; j<N; j++) {
            if(A[i][j] == 1)
                printf("x");
            else
                printf(" ");
        }
        printf("|\n");
    }
    for(i=0; i<N+2; i++)
        printf("-");
    printf("\n");

    printf("Press [ENTER] for the next generation.\n");

    fclose(file1);

    while(getchar()) {
        system("clear");
        clone(growDie,stackTop,CLONE_VM|CLONE_FILES,NULL);
        display(N);
    }
}

GDB错误

我认为问题出在stackTop，但我不确定。
