semi-top(offtop?):
About the game code - i found a good CDDA analysis via PVS-Studio, can it help at some way? More globally than this problem. (original link: https://habr.com/ru/company/pvs-studio/blog/449472/ )

@AnonimusC: Those are related to code quality, not speed. AND most if not all of those have already been fixed.

@AnonimusC , ZhilkinSerg commented on the original article and he regularly uses PVS-studio or similar static analysis tool to find and fix such issues.
