一个跟踪算法的程序

程序能够正常运行，效果也正确。但是在执行return 0后发生错误异常如下：

First-chance exception at 0x773cc398 in CompressiveTracking.exe: 0xC0000005: Access violation writing location 0x00000035.
Unhandled exception at 0x773cc398 in CompressiveTracking.exe: 0xC0000005: Access violation writing location 0x00000035.

不知道是程序内部出现内存泄露还是这个程序以外的问题（觉得是后者）

如果是程序外的问题该如何解决

谢谢
