Re: Re: making perl more forgetting

It sounds like the only solution that is guaranteed is to use ASM and/or a C compiler with optimizing turned off. (Is there an Inline::ASM?)

Well, it might be easier to write your code in such a way that the optimizer can't optimize it away the overwriting of the memory - for instance, by reading it back and doing something with those results. (Of course, you still might be outsmarted by your OS - if you're unlucky your rewrites won't go futher than the cache before the program is terminated, and the memory pages invalidated).
