oof, if that's the same issue i'm a bit worried about possible silent misevaluations

In reply to @k900:0upti.me
Which libraries?

In reply to @aleksana:mozilla.org
How do we make sure that the bug definitely doesn't happen with nix 2.18 and newer libraries in tree

In reply to @k900:0upti.me
Do we revert again

#!/usr/bin/env bash
set -e

RRDIR=$HOME/.cache/rr-testing

gorun() {
    for (( i=0; i < 40; i = i + 1 )); do
        _RR_TRACE_DIR=$RRDIR rr record --chaos -- nix eval --no-eval-cache .#nixosConfigurations.snowflake
    done
}

while true; do
    rm -rvf "$RRDIR"
    gorun
done

btw this is my bad script

ok i didn't quite get that script right. here's one that works and also warms the computer a bit more:

#!/usr/bin/env bash
set -e

RRDIR=$HOME/.cache/rr-testing

gorun() {
    for (( i=0; i < 40; i = i + 1 )); do
        _RR_TRACE_DIR=$RRDIR parallel -N0 --verbose --halt-on-error 2 --lb rr record --chaos -- nix eval --eval-store "$(pwd)/store" --no-eval-cache .#nixosConfigurations.snowflake.config.system.build.toplevel ::: {1..10}
    done
}

nix --version

while true; do
    rm -rvf "$RRDIR"
    gorun
done

Hey, I just got a segfault on nix flake check on nix (Nix) 2.24.6

checking flake output 'apps'zsh: segmentation fault (core dumped)  nix flake check

In reply to @mightyiam:matrix.org
The flake we were working on is private, sorry. Not sure what more I can do. Perhaps it will occur again...
