Network failure causes Mac client 4.20 to crash

Nearly every network problem ( it looks like network connectivity problem at least ) causes 4.20 Mac client to crash with coredump instead of proper reconnect. Sometimes this problem occurs in much severe form e.g. computer become frozen, just for reference - similar symptoms was not observed during usage of any other applications e.g. that particular problem persists somewhere in client's code & not related to Mac OS / Macbook hardware. I could narrow this "freeze" problem further - this happens when network failure occurs during first connection establishment to server. Similar bugs already reported in less general manner e.g. "Infinite reconnect loop" etc. Just for one game, client crashed 9 times in row due this reconnection loop - change of wi-fi network postponed this issue somehow.
