Valgrind memcheck FR 2.2.1shows memory leak

I installed FR 2.2.1 from git on one of our radius servers on April 22. After installation, I ran valgrind memcheck against radiusd binary and it showed no memory leak. A few days later now, I ran valgrind again. It showed memory leak. I am not sure what caused it. I have valgrind memcheck output for you to review but its 7MB. I don't know if it's too big for posting or attaching it on this list. Please let me a way to post/send it without causing any trouble. I plan to upgrade our production server to 2.2.1 early next week and I am a little concerned with this memory leak check thing.

Here is the radiusd -v:
