Dear all,
I'm running some tests with cvtColor and valgrind reports a memory leak.
Some information about the environment:
$ lsb_release -a
No LSB modules are available.
Distributor ID: Ubuntu
Description: Ubuntu 14.04.2 LTS
Release: 14.04
Codename: trusty
$ uname --all

$ valgrind --version
valgrind-3.10.0.SVN
This is a short standalone sample:
$ cat test.cpp
#include
#include
#include
int main()
{
std::cout << cv::getBuildInformation() << std::endl;
cv::Mat src = cv::Mat::zeros(5, 5, CV_8UC3);
cv::Mat dst;
cv::cvtColor( src, dst, CV_BGR2GRAY );
}
$ g++ -Wall -Wextra -Werror -Weffc++ -ansi -pedantic -O2 test.cpp -o test $(pkg-config --cflags --libs opencv)
And the output from valgrind:
$ valgrind --leak-check=full ./test

What am I missing in order to fix this memory leak?
Thanks and best regards!
====================
[UPDATE 2015-07-20]
After some more tests, I found out that the memory leak occurs when OpenCV is built with TBB support.
These are the results using OpenCV 2.4.11.
Building OpenCV:
$ cmake -D CMAKE_BUILD_TYPE=RELEASE -D CMAKE_INSTALL_PREFIX= ..
$ make -j9
$ make -j9 install
Building sample:
$ g++ -Wall -Wextra -Werror -Weffc++ -ansi -pedantic -O2 test.cpp -o test -I/include/opencv /lib/libopencv_core.so /lib/libopencv_imgproc.so
And the output:
$ LD_LIBRARY_PATH=/lib/:$LD_LIBRARY_PATH valgrind --leak-check=full ./test
