Stack Smash Protection sounds like a cool feature to me. I don't know what the performance impact is, but as a developer even if it is to slow to use by default I would love to have it intergrated into the gcc shipped by Fedora to make debugging easier.

you can use jakub's gcc 4 / glibc rpms and something like this too

PAX uses tricks to get a non executable stack, and assignes random addresses to PIE executables, which Fedora already has in the form of Exec Shield, good! But if I undertand it correctly PAX does more for example also make data pages non executable, this might be something worth looking into.

execshield makes data pages also non executable
