I discovered I can use Keeping this issue up since it affects unstable. |

Thanks for the report. Looks like something fishy's going in the git fetcher (though I've no idea what). I can't reproduce though because the repo is using git-crypt for some files so I can't evaluate it. Do you think you could add a branch with all the encrypted files replaced by a (dummy) clear version to see whether it can be reproduced? |

I wonder whether this is the same issue as #6554 (which is also about a sigsev related to the git fetcher) |

The git fetcher code used to dereference the (potentially empty) `ref` input attribute. This was magically working, probably because the compiler somehow outsmarted us, but is now blowing up with newer nixpkgs versions. Fix that by not trying to access this field while we don't know for sure that it has been defined. Fix #6554

Describe the bug
So I recently wiped my laptop to change its filesystem from btrfs to ext4, hoping for a little performance improvement (every bit counts at its age). I was able to re-partition my disk and re-install NixOS smoothly on my laptop. (Here's my NixOS config.)
But I cannot build my home-manager configuration.
I manage my home-manager config with flakes. To build it for the first time on a fresh system, I'm trying to use
nix build --no-link ~/.config/nixpkgs/#homeConfigurations.<machine_name>.activationPackage. However, this fails with an address boundary error (SIGSEGV).Steps To Reproduce
Steps to reproduce the behavior:
nixUnstable. My system config above now usesnixFlakes, which is not affected by this bug.~/.config/nixpkgscd ~/.config/nixpkgsnix build --no-link ~/.config/nixpkgs#homeConfigurations.littlepony.activationPackageYou should get something like
nix build ... terminated by SIGSEGV (Address boundary error)Expected behavior
I should be able to build my home-manager configuration successfully
Additional context
I haven't found anything online about this. I've tried running it with
env GC_DONT_GC=1, but that didn't fix the issue.Here's gdb output and an strace that might help.
Thank you in advance for any help, workarounds, or suggestions :)
