Title:
  coreutils-from-uutils performs badly and crashes

Status in rust-coreutils package in Ubuntu:
  Opinion

Bug description:
  On Ubuntu 25.10 with the latest updates as of 2025-12-08, I see stat crashing randomly (reported separately over ubuntu's bug reporting tool) without any obvious errors being visible to me as a user except this dmesg entry: coredump: 7808(stat): over core_pipe_limit, skipping core dump
  However make parsing a Makefile is over 100 times slower with the rust coreutils than the gnu ones, so I assume stat crashing in the background has some noticeable performance hit. But I would expect make crashing then too. Therefore I created this issue because I suspect some error codes are not being treated accordingly. Anyway it could be something else wrong with coreutils-from-uutils performance wise as well.

  The only acceptable solution for me was to use the gnu coreutils as a workaround for now.
  sudo apt-get remove coreutils-from-uutils --allow-remove-essential

  I'm concerned the coreutils-from-uutils is not yet production ready.
