写入位置 0xCDCDCDCD 时发生访问冲突等

debug时VS为了更快得帮程序员检测出内存问题,因此对初始化后的内存和释放后的内存做了一些处理,有:

0xcdcdcdcd - Created but not initialised (分配空间了,但是没初始化比如说刷成0,没调用构造函数)

0xdddddddd - Deleted (指针已经delete了，还调用它，也就是调用了已经delete的内存...)

0xfeeefeee - Freed memory set by NT's heap manager

0xcccccccc - Uninitialized locals in VC6 when you compile w/ /GZ

0xabababab - Memory following a block allocated by LocalAlloc()
