Hi again,
I was able to reproduce it on hydra.gnu.org with:
guix copy --to=hydra.gnunet.org
/gnu/store/gi7r1v65zqhh8riqprq8nchfc9v9k156-guix-current
which leads most of the time to SIGSEGV (I couldn’t get the SIGSEGV on
my laptop):

Unfortunately, when running under “valgrind --trace-children=yes”, it
doesn’t segfault and Valgrind doesn’t report anything interesting
(neither on hydra.gnu.org nor on my laptop).
I built libssh and guile-ssh with -fsanitize=address on my laptop but
that doesn’t report anything useful either.
Suggestions welcome!
