I'll have a good look at "man setarch" and also try this out in the next couple of days. Quick question: from "man setarch", the effect of using -R is "turns on ADDR_NO_RANDOMIZE". Is it possible to use this flag ADDR_NO_RANDOMIZE somewhere that will force that binary to use that option always? I've read something about ELF headers, I wonder if that is something that could be set there, and if it is, how do I change the ELF headers to set it? Thanks! Filipe
