torsocks works with wget but fails git-clone: "unable to lookup symbols in libc.so.6"

[Mekeor Melire]

Problem
=======

This works fine:

    $ torsocks wget http://github.com/mekeor/config

This fails:

    $ torsocks git clone http://github.com/mekeor/config
    1491426097 ERROR torsocks[25849]: Unable to lookup symbols in 
libc.so.6((null)) (in init_libc_symbols() at torsocks.c:239)

Torifying browsers like netsurf-gtk, surf, w3m either also fail or don't
succeed. Using "torify" instead of "torsocks" results in the same.


Information
===========

My config.scm contains:

    (tor-service)

My whole config is available at:

    https://github.com/mekeor/config/blob/master/etc/guix/config.scm

The error is printed on this line in the code of torsocks:

    https://github.com/dgoulet/torsocks/blob/master/src/lib/torsocks.c#L239

I'm using version 20170405.20 of Guix (on GuixSD).


Question
========

Why does torsocks work with wget but doesn't work with git-clone? What
does the error mean? What does it have to do with libc? Is anybody able
to reproduce this?
