I wondered, how valgrind could help. It seems, it noisy, some findings should be muted. but it didn't give a clue on what's going on

@chipitsine Your valgrind setup is not right hence those false positives. See below for more details:

These are not memory issues so valgrind won't find anything (it is still valgrind clean on my side).
