is_block_type_valid（header_block_use）错误

Question

我正在尝试在方法中使用strtok拆分字符串，但是代码不断崩溃。我想这跟calloc有关。有什么建议吗？如果将其整体放在主体中，则代码可以正常工作，但我需要一种方法。错误也很模糊，所以我真的没有任何方向。

int main(void) {
    char v[] = "32939/40742/40042  32940/40743/40043 32944/40747/40044 32943/40746/40045";
    printf("Length: %d", strlen(v));
    int* parts = split(v, " ",strlen(v));
    for (int i = 0;i < 4;i++) {
        printf("Part %d : %d\n", i, parts[i]);
    }
    free(parts);
    return 0;
}

int* split(char* str, char* delimiters, int size) { // Method to split given string into required face tokens
    char** tokens = (char**)calloc((size+1), sizeof(char*)); // Array to store all tokens
    for (int i = 0; i < (size + 1); i++)
        tokens[i] = (char*)calloc((size + 1), sizeof(char));

    char* temp = (char*)calloc((size + 1), sizeof(char)); // Array to store temp tokens

    int index = 0;
    temp = strtok(str, delimiters);
    while (temp != NULL) { // Split using spaces
        if (index < (size + 1)) {
            tokens[index] = temp;
        }
        index++;
        temp = strtok(NULL, " ");
    }

    int* parts = (int*)calloc((size + 1), sizeof(int)); // Array to store parts of face
    for (int i = 0;i < index;i++) { // Split using /
        temp = strtok(tokens[i], "/");
        parts[i] = atoi(temp);
    }

    //free tokens, free temp
    for (int i = 0; i < (size + 1); i++) //Crashing here most of the time
        free(tokens[i]);
    free(tokens);
    free(temp);
    return parts;
}
