OpenCV2.4.9自带的Camshift程序,在VS2010中运行时频繁异常终止

如题,我在运行OpenCV2.4.9自带的camshift.cpp时,几乎每次运行都异常终止。我发现一般情况下,是在跟丢目标(目标移动稍快)时,或者Smin值调节过大时异常终止。
提示为:
Runtime Error!
This application has requested the Runtime to terminate it in an unusual way.
我的OpenCV配置应该没有问题,运行其他一些程序的时候也没有类似问题。
按照一些网上的说法,似乎与内存管理有关,但是本人对代码理解尚不透彻,望有高手能帮忙找出解决方案,OpenCV自带的这段代码是否需要修改。
希望能够得到具体的回答。
很惭愧,并无c币相赠。

    用调试的方式运行,然后看看能不能得到跳出异常的地方呢。

    有时也提示:
    0x75f1c42d (KernelBase.dll) 处有未经处理的异常: Microsoft C++ 异常: 内存位置 0x0048e3ac 处的 cv::Exception

    在配置OpenCV库的时候,有把debug和release版的库混着配置吗?如果有的话分开配置,不然运行的时候就会出现这个错误
