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!
