Expression class dosen't clear cv::Mat correctly about ofxfacetracker HOT 3 OPEN

can you provide more info about how you're resizing the expressions vector? cv::Mat are reference counted and shouldn't have to be manually released because the destructor of the vector should call the destructor of the Mat

from ofxfacetracker.

It calls the cv::Mat destructor then EXC_BAD_ACCESS. I'm not really doing anything, this is with the example.

I think the issue is that calling resize may invoke the copy constructor of the contained object: http://stackoverflow.com/questions/9591840/does-resizing-an-stl-vector-erase-invalidate-its-previous-contents
