main panicks when using uutils in place of GNU coreutils

[siraben]

I was reviewing a Nixpkgs PR (NixOS/nixpkgs#116274 (comment)) which intends to add a new stdenv (the default build environment for packages in NIxpkgs) based on uutils-coreutils instead of GNU coreutils. The good news is that some packages build successfully such as bash, tmux, guile, fish. However several common packages do not, here's an example backtrace when compiling miranda (it compiles successfully with GNU coreutils).

[nix-shell:~/nixpkgs]$ nix-build --show-trace -E 'with import ./. { }; miranda.override { stdenv = stdenvUutilsCoreutils; }'
these derivations will be built:
  /nix/store/5dih65675n9dkzdvr4h5dv8k0k9bqxyq-miranda-2.066.drv

Please don't open bugs for "this program foo doesn't work with rust/coreutils"

Instead, please provide a test case like "rm doesn't work with options --foobar"

And main isn't panicking, it is

  12:     0x55555593ab35 - uu_cp::copy_file::h61df3196d7a7b976

So, please open a new bugs to make it more actionable! :) thanks!
