Created attachment 126433 [details] garbage.
Don't do that then. Only objdump/readelf/elflint/strings/etc. are supposed to be garbage proof, even ther eit took many weeks to make them garbage proof to some extent. as/ld/gcc being totally garbage proof is many men-years of work, it was decided both by us and upstream that's not worth it.
