From the GCC documentation:
I wonder why? |

This is a mass rebuild so please target staging. |

This feels like a duplication of #102251. |
g++ used for SIMD operations will mangle names. Options are to either disable SIMD, or provide deterministic mangling via -frandom-seed

g++ used for SIMD operations will mangle names. Options are to either

Things done
Found that disabling SIMD provided a reproducible build, but then found that only providing
-frandom-seed=123456provides deterministic name mangling and order in the resulting binary.sandboxinnix.confon non-NixOS linux)nix-shell -p nixpkgs-review --run "nixpkgs-review wip"./result/bin/)nix path-info -Sbefore and after)
