[-- Attachment #1 --] Hello Ganael, I didn't know that were a way to disabling aslr in a port! This is really nice. I'm having a lot of segfaults and tab crashing on firefox @aarch64 and mikael@ sugested turning it off to see if it fixes. I will test first with sysctl aslr off and if it works I will test port option. So syntax is: USES+= elfctl ELF_FEATURES= +noasr:<path_to_something>?
