When we run our application under valgrind sometimes it is trowing this warning. Note that it does not happen every time and we did not manage to reproduce it in a small application. We running our application on Ubuntu 16.04.5 LTS machine and using gcc 5.4.0 20160609 compiler. Also we are using valgrind-3.14.0.
