--- Comment #1 from Cody Schafer <gcc_bugs at codyps dot com> --- It appears that commit 8e18705e1fb8213834b09c91c3ed7b15c8540d59 Author: msebor <msebor@138bc75d-0d04-0410-961f-82ee72b054a4> Date: Fri Jul 20 20:51:20 2018 +0000 PR middle-end/82063 - issues with arguments enabled by -Wall Might be the change in `-Wstack-usage=0` behavior. Seems likely that this also affects `-Wframe-larger-that=` and `-Wlarger-than=` as they received similar `gcc/common.opt` modifications. This also introduced the documentation for `-Wno-stack-usage`.
