[Solved] CascadeClassifier.detectMultiScale crash on Mac OSX

I'm using OpenCV 3 on Windows, Linux and Mac. My program goes to crash when calling the function CascadeClassifier::detectMultiScale. This happens only on Mac but not on Linux, Windows. This is the Mac bug report: 4 libopencv_objdetect.3.0.dylib 0x000000010fd68486 cv::CascadeClassifier::detectMultiScale(cv::_InputArray const&, std::__1::vector, std::__1::allocator>>&, double, int, int, cv::Size_, cv::Size_) + 214 25 ssssss.ComputerVisionStudio 0x000000010e444cda QThProcessImage::DetectObjects(cv::Mat, cv::CascadeClassifier&, cv::CascadeClassifier&, QString) + 378
