There's something wrong with that test if it's forcing you to make a
normally writable sysctl read-only via kernel patch.
One would expect a sysctl like /proc/sys/kernel/randomize_va_space to
be writable by root. Changing that would confuse a lot of people.
I can't find any documentation for this tool, only broken links on the
web. Perhaps it has been fixed to make more sense?
