libcstl中的list没法插入自定义数据

一开始运行出错，开启debug以后发现在push自定义对象的时候调试器提示找不到一个叫/XXX/XXXX/XXXX/libcstl-2.3.0/src/cstl_list_private.c</br>
而那个路径正是我进行安装的路径，安装完以后我把安装包给删除掉了，所以它找不到。这样的话，我们在一开始安装的时候就要注意最好先把tar.gz解压出来的文件夹放到特定文件夹，比如/usr/local/下，这样不会在安装完成后被误删，也比较方便查找。</br>
但是再次调试的时候却发现插入操作死在了调用_my_copy()函数那里，里面设置了一个int型临时变量i_temp用来作中间值方便调试，调试过程中发现i_temp成了一个非常小的负值。
但是直接调用_my_copy()是能正确运行的。</br>
鉴于程序呈现出这种尿性，我觉得应该是cstl它自己设计得不够健壮。。。不然实在是说不通程序会死在_my_copy()函数那里。
其实最后我发现copy函数形参里的cpv_source它的地址为0x1，明显就不可能。这个就关系到cstl对list的内部实现了，不想再深入去了解，暂时到此为止。
最后还是照惯例贴个代码：
