C 动态阵列被信号 SIGSEGV 中断

问：

我正在尝试用 C 编写一个动态数组（大小和类型是动态的）。

首先，我编写了一个函数来初始化数组。输入是一个枚举 （TYPE），根据此参数的值，我为相应的类型分配内存。

这是我初始化数组的方式：

...

typedef enum {
    CHAR,
    INT,
    FLOAT,
    DOUBLE,
    BOOLEAN,
} TYPE;

...

struct vector_result {
    TYPE type;
    int len;
    void* data;
};

...

struct vector_result DSTR_vector_init(TYPE type){
    void* data;
    switch (type) {
        case CHAR:
            data = (char*) malloc(0);
            break;
        case INT:
            data = (int*) malloc(0);
            break;
        case FLOAT:
            data = (float*) malloc(0);
            break;
        case DOUBLE:
            data = (double*) malloc(0);
            break;
        case BOOLEAN:
            data = (bool*) malloc(0);
            break;
        default:
            fprintf(stderr, "unknown type to initialize vector\n");
            exit(EXIT_FAILURE);
    }
    struct vector_result result;
    result.type = type;
    result.data = data;
    result.len = 0;
    return result;
}

这就是我调整大小并将数据附加到列表的方式：

void DSTR_vector_push(struct vector_result* vector, void* value){
    vector->len++;
    switch (vector->type) {
        case CHAR:
            vector->data = (char*) realloc(vector->data, get_type_size(vector->type) * vector->len);
            ((char*)vector->data)[vector->len-1] = *(char*) value;
            break;
        case INT:
            vector->data = (int*) realloc(vector->data, get_type_size(vector->type) * vector->len);
            ((int*)vector->data)[vector->len-1] = *(int*) value;
            break;
        case FLOAT:
            vector->data = (float*) realloc(vector->data, get_type_size(vector->type) * vector->len);
            ((float*)vector->data)[vector->len-1] = *(float*) value;
            break;
        case DOUBLE:
            vector->data = (double*) realloc(vector->data, get_type_size(vector->type) * vector->len);
            ((double*)vector->data)[vector->len-1] = *(double*) value;
            break;
        case BOOLEAN:
            vector->data = (bool*) realloc(vector->data, get_type_size(vector->type) * vector->len);
            ((bool*)vector->data)[vector->len-1] = *(bool*) value;
            break;
        default:
            fprintf(stderr, "unknown type to initialize vector\n");
            exit(EXIT_FAILURE);
    }
}

下面的代码正在初始化并将一个项目附加到列表中

struct vector_result int_vec = DSTR_vector_init(INT);
DSTR_vector_push(&int_vec, 10);

但是我在执行后收到此错误：

Process finished with exit code 139 (interrupted by signal 11: SIGSEGV)

问题是什么？
