The github issue template says:
If you need help using your system and are unsure if this is a bug with Nixpkgs, please consider asking for help on the NixOS Discourse or the NixOS Matrix Space before opening an issue.
So I’m asking here like it says.
I’m having a problem with kicad where the 3D viewer doesn’t show anything. If I click “View” → “Update”, I get a segmentation fault. I think it’s related to the nix package, because I’ve never had this problem on Arch, but I’m not 100% sure. How do I know?
❯ kicad
zsh: segmentation fault (core dumped) kicad
Maybe coredumpctl has more info about the segfault.
Thanks for your comment. It’s a good idea. I don’t have experience analyzing core dumps. I demangled the names, but they don’t mean much to me.
