Re: about the virtual address space of processes

Why would heap randomization prevent me from getting a same address?

Anyways, usually, even when not guaranteed anything, you'd expect to be able to in practice get the same address. I know recent Red Hat distributions use addressspace randomization which easily could interfere. I suppose you are using Debian:

`- Debian GNU/Linux - The power of freedom

(ugh) and I do not know if it also does. Does it?

Just now see that heap randomization is in fact a standard kernel feature these days and therefore likely what is hitting you. You can disable it under CONFIG_EMBEDDED.
