c - 使用 MPI_Type_create_subarray 传递 3D 数组

Question

double*** esfld;

void allocate()
{ //... malloced all three dimensions of the esfld 3D array }

void initialize()
{ //... Initialize every element in all three dimensions of esfld to zero}

MPI_Datatype make3dtype()
{
    int array_of_sizes[]={nz,ny,nx};
    int array_of_subsizes[]={nz,ny,nx};
    int array_of_starts[]={0,0,0};
    MPI_Datatype arr3d;
    int ndims=3;
    MPI_Type_create_subarray(ndims,array_of_sizes,array_of_subsizes,array_of_starts,MPI_ORDER_C,MPI_DOUBLE,&arr3d);
    MPI_Type_commit(&arr3d);
    return arr3d;
}

void sendData()
{
    MPI_Datatype arr3d=make3dtype();
    MPI_Type_commit(&arr3d);
    MPI_Send(esfld,1,arr3d,1,1,MPI_COMM_WORLD);
}

void receiveData()
{  
   MPI_Status status;
   MPI_Datatype arr3d=make3dtype();
   MPI_Type_commit(&arr3d);
   MPI_Recv(esfld,1,arr3d,0,1,MPI_COMM_WORLD,&status);

}

int main()
{
    MPI_Init(&argc,&argv);
    allocate();
    initialize();

    int size,rank;
    MPI_Comm_size(MPI_COMM_WORLD,&size);
    MPI_Comm_rank(MPI_COMM_WORLD,&rank);

    for(int i=0;i<5;i++){
        if(rank==0){
            sendData();
        }
        else if(rank==1){
            receiveData();
        }
    }
    MPI_Finalize();
    return 0;
}

由于此代码而获得段错误。段错误不在分配或初始化函数中，我已经尝试过了。它是导致这种情况的 arr3d 类型的发送/接收。我究竟做错了什么 ？
