Is this not pretty much equivalent to a volatile read where you're forcing the compiler to not optimise this unused thing away? In guard-regions I set:#define FORCE_READ(x) (*(volatile typeof(x) *)x) For this purpose, which would make this: FORCE_READ(addr); FORCE_READ(&addr[pagesize]);Hmmm, a compiler might be allowed to optimize out a volatile read.
Looking into this, the compiler should not be allowed to do that. So FORCE_READ() should work!
