Similar issue but not on Python. It seems the only change from 2.0.0 to 2.1.0 
is that the new pointer wrap type: cv::Ptr<CvMat> is used instead of CvMat *, 
and the function fails at the deconstruction. This new feature might be 
unstable as I guess. Try modify the type back to CvMat * for that function and 
rebuild the library.
Good luck.

Hi,

Thanks for raising the issue. I'll take a look. Sorry for my slow response as 
I've just got a new job and been busy settling in a new place.

Cheers,

I'd like to confirm xiaobotthu's observation. I rebuilt OpenCV 2.1 with that 
small fix and the pyrMeanShiftFiltering function worked. Though this issue is 
OpenCV's bug, I appreciate that you have filed it.
