--- Comment #1 from Dirk-Willem van Gulik  ---
Tried and tested code (https://github.com/gnea/grbl) grows from 28k to about
36k (so a 1/3 change) when going gcc version 7.3.0 (GCC) to gcc version 12.2.0
(GCC) for GCC-AVR. 

Size increase is across the board according to avr-nm -l --size-sort ; with
pretty much sensible flags provided:

avr-gcc -Wall -Os -mcall-prologues  -fdata-sections -ffunction-sections
-flto
