Yes, it's because of some update around estimated memory calculation ; recursion function detection has been improved but it would seem that's not enough, there is still a lot of legit context. I'm going to disable estimated memory usage or enabling it through a compiler option but it will be disabled by default in next build. Also, this is not that useful, it could help only if you have big plugin and you want to know how much more memory you need to add (#pragma dynamic).
