error onOcclusion

[C-peng]

when evaluateocclusion is true,the project dies. what is wrong?

[C-peng]

The error on the code"cv::meanStdDev(cv::Mat(frame[1], boundingBoxModified & imageRect), mean, stddev, occluder);", what is the cause?

The error on the code"cv::meanStdDev(cv::Mat(frame[1], boundingBoxModified & imageRect), mean, stddev, occluder);", what is the cause?

Have you solved the issue? Thanks

I also get the same error. It happens when I walk between the camera and the object that gets tracked, meaning I occlude the object that gets tracked. Here is also a backtrace from gdb (paths and other data are removed).
