https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=3D241905 Conrad Meyer <cem@freebsd.org> changed: What |Removed |Added ---------------------------------------------------------------------------- CC| |cem@freebsd.org --- Comment #2 from Conrad Meyer <cem@freebsd.org> --- OpenBSD has an (?)interesting solution to this problem: they hack in an ".openbsd.randomdata" section to their ELF objects and initialize it before= an object's ctors run. (Of course, __stack_chk_guard is placed in that sectio= n.) I think this could also be solved by ensuring the __guard_setup ctor runs first, in some implementation-defined way. --=20 You are receiving this mail because: You are the assignee for the bug.=
