Hi, I have the same problem. In my case, the error occurs when the GPU version v Haar features is used. I have no idea how fix this problem, nevertheless, i train my own haar classifier using old haartraining due to GPU (this is note in the opencv doc) and if i use the classifier after 16 stages the detection works, however if i used it after 19 stages this error occurs.

Did you fix the problem?
