In practice with libstdc++ you need to produce a comparator which is not a pure function, which is obviously not easy in nix… but you can do that, you can swap pointers from out-of-bounds of your list.

oh yeah i didn't find it by mistake, i was reading the code to find memory bugs :3
builtins.sort takes a nix lambda as a comparator, and calls C++'s std::stable_sort… but std::stable_sort is UB if the comparator is not a valid partial ordering!

i was messing with a nix interpreter memory-corruption recently and discovered that the repl has special-case support for printing null object pointers :P

do u think maybe theres something u could have done to make the code look nicer too, indentation-wise? 😭

any idea if the memory encryption that T234 has is present/enabled?

since the ascription derfc i guess there at least aren't any syntactic ambiguities… :3

i've been working on a specialised hypervisor for running nix builds, which involves structs holding raw pointers to guest memory (which stops rust automatically deriving send/sync) – i'm not really confident that code is correct rn, i just wanted to get it working and will make it woke later

i do not feel safe and protected because i have typed "unsafe impl Send" and "unsafe impl Sync" a lot recently 😔
