Hey Lee, I'm confused because I had the feeling someone had already reported a bug, but apparently not, although there's a merge request on Salsa (https://salsa.debian.org/corsac/hardening-runtime/-/merge_requests/7 ). I tried to contact Kees Cook on Mastodon about that (https://mastodon.social/@corsac/111811338805308373 ) but it didn't go anywhere. Adding Kees to the CC: list as it might be a better way to reach him :) Regards, -- Yves-Alexis
