我正在使用OpenCV的SVM，似乎在train_auto函数中存在内存泄漏。
我在Boost::Test环境中运行它，因为它会在运行时发现泄漏时警告用户。
当我注释掉train_auto行时，没有泄漏。
这是完整的代码：
#define BOOST_TEST_MODULE SomeTestModule
#include <boost\test\included\unit_test.hpp>
#include "opencv2\ml\ml.hpp"
#include "opencv/cv.h"
BOOST_AUTO_TEST_CASE(SomeTestname)
{
// Prepare matrix of class numbers (few ones, few zeros)
cv::Mat classes = cv::Mat::ones(10, 1, CV_32FC1);
cv::vconcat(classes, (cv::Mat::zeros(10, 1, CV_32FC1)), classes);
// Prepare matrix of 2-d feature vectors (random :D )
cv::Mat featureVectors(20, 2, CV_32FC1);
cv::randu(featureVectors, -1, 1);
// Set up SVM parameters
CvSVMParams params;
params.svm_type = CvSVM::C_SVC;
params.kernel_type = CvSVM::LINEAR;
params.term_crit = cvTermCriteria(CV_TERMCRIT_ITER, 100, 1e-6);
// And do the training!
CvSVM svm;
svm.train_auto(featureVectors, classes, cv::Mat(), cv::Mat(), params);
}
输出（在运行Boost::Test可执行文件后）是：
Running 1 test case...

这是OpenCV的错误还是我对图书馆的错误使用？
如何避免这种泄漏？
