bug#23389: segfault for non-root user

[Myles English]

Hello,

Just installed binary x86-64 nix on Arch Linux as per instructions here:

http://www.gnu.org/software/guix/manual/guix.html#Binary-Installation

The install for root when well and the hello sample package installed
fine.  Then I went to setup my user as described here:

http://www.gnu.org/software/guix/manual/guix.html#Application-Setup

but got a segfault at:

$ guix package -i glibc-locales

and in fact even just

$ guix

I don't know if this backtrace is useful but here it it:

Is LD_LIBRARY_PATH or LD_PRELOAD set in your environment?

What happens if you run:

  env -i `type -P guix` --help

What does “info files” say in GDB?

Thank you for the bug report!

This was set:

LD_LIBRARY_PATH=/home/myles/GNUstep/Library/Libraries:/usr/lib

so I uninstalled GNUstep and rebooted, LD_LIBRARY_PATH is unset and this
works:

$ guix package -i glibc-locales

> What happens if you run:

$ env -i `type -P guix` --help
zsh: bad option: -P
Usage: env [OPTION]... [-] [NAME=VALUE]... [COMMAND [ARG]...]
Set each NAME to VALUE in the environment and run COMMAND.

Mandatory arguments to long options are mandatory for short options too.
  -i, --ignore-environment  start with an empty environment
  -0, --null           end each output line with NUL, not newline
  -u, --unset=NAME     remove variable from the environment
      --help     display this help and exit
      --version  output version information and exit

A mere - implies -i.  If no COMMAND, print the resulting environment.

N/A

Thank you for the help!  'Bug' closed?

P.S. now firefox gives me a segfault, I think there are other issues here.

Great.

Then something like:

  env -i `which guix` --help

Anyway, the rest of your message confirms my intuition.

Thanks,
Ludo’.
