The core is at http://hyperdev.fr/static/gnunet-guile-1.gz
To reproduce follow those steps
I use guile-2.2.3 from guix.
To reproduce the bug you need guix:
git clone git://gnunet.org/gnunet-guile2.git
Then install gnunet:
guix package -f guix.scm
Then compile the gnunet-guile with:
./bootstrap && ./configure && make
You need to run gnunet services, for that do the following:
mkdir /tmp/gnunet/p2
gnunet-arm -c etc/p2.conf -s
Then inside the gnunet-guile2 directory, run the following command:
./pre-inst-env guile test-sigpwr-fail.scm
