Hi, I was able to generate a core dump. Here is the output of the command:
$ nix-env -i emacs ... *** Downloading ‘http://nixos.org/binary-cache/nar/1g14fszfd2986sjcjyhn16vimcirm8chsxc1j3f9v71mysx96l0q.nar.bz2’ to ‘/nix/store/jpxj8z3mc7fjdnby58001k8icisjiis0-lzo-2.06’... % Total % Received % Xferd Average Speed Time Time Time Current Dload Upload Total Spent Left Speed 100 78256 100 78256 0 0 344k 0 --:--:-- --:--:-- --:--:-- 347k fetching path `/nix/store/jpxj8z3mc7fjdnby58001k8icisjiis0-lzo-2.06' failed due to signal 11 (Segmentation fault) fetching path `/nix/store/0pdfk07adfpjxx0hjgdb3mk3qya1kxlg-libungif-4.1.4.tar.gz'... killing process 700 error: some substitutes for the outputs of derivation `/nix/store/jq8qd6484m700f19ym1ssk85hh3v4qiv-lzo-2.06.drv' failed; try `--fallback' Actually I got two files (I expected only one), I don't know why: # ls -la /cores/ total 1267808 drwxrwxrwt@ 4 root admin 136 Mar 28 08:37 . drwxrwxr-x 38 root admin 1360 Mar 28 08:11 .. -r-------- 1 root admin 324558848 Mar 28 08:37 core.688 -r-------- 1 root admin 324558848 Mar 28 08:37 core.694 But now I don't know how to get the stack trace. I assume I should run $ gdb <progname> <corefile> (gdb) bt But who is <progname> ? I can send you the core dumps. Or I can test some commands if you give me more suggestions.
