I am trying to train my tree but the app crashes and shows "bad_alloc" or "Fatal Signal 11". I have been searching for an answer but I have not found anything useful... Could someone help me?:(
Mat data=new Mat(NUMBER_SAMPLES, ATTRIBUTES_PER_SAMPLE,CvType.CV_32F,Scalar.all(0) );
I fill them from a CSV and it makes it OK because after that the values are the same as in the CSV, but the problem comes when I try to use this to train my decision tree:
DTrees d=DTrees.create();
d.setMaxDepth(25);
d.setPriors(new Mat());
d.setMaxCategories(6);
d.train(samples, Ml.ROW_SAMPLE, responses);
This is the log:

If I change
setMaxDepth(25);
to for example
setMaxDepth(5);
the APP crashes because of a "Fatal Signal 11"

¿Any suggest? I don't know how to solve it :(
Thanks in advance!
