In _very_ rare cases (I had about 7 cases out of 32200 files!), the order of how inherit-from bindings are printed when using `nix-instantiate --parse` gets messed up. The cause of this seems to be because the std::map the bindings are placed in is keyed on a _pointer_, which then uses an [implementation-defined strict total order](https://en.cppreference.com/w/cpp/language/operator_comparison#Pointer_total_order). The fix here is to key the bindings on their displacement instead, which maintains the same order as they appear in the file. Unfortunately I wasn't able to make a reproducible test for this in the source, there's something about the local environment that makes it unreproducible for me. However I was able to make a reproducible test in a Nix build on a Nix version from a very recent master: nix build github:infinisil/non-det-nix-parsing-repro Co-authored-by: Robert Hensing <roberth@users.noreply.github.com> |
