--- 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.
