May I ask you another test, please ?

# Clone gnustep-base
git clone https://anonscm.debian.org/git/pkg-gnustep/gnustep-base.git

# Enter in gnsutep-base dir
cd gnustep-base

# Install build-dependencies
# (libffcall1-dev IS REPLACING libffi-dev)
apt-get --no-install-recommends install debhelper gnustep-make gobjc-5
libxml2-dev libxslt1-dev libgnutls28-dev zlib1g-dev m4
libavahi-client-dev libicu-dev dh-autoreconf dh-exec texinfo
texlive-latex-base texlive-fonts-recommended xml-core build-essential
libffcall1-dev

# 1- gcc-5 with libffcall1-dev

# Make sure libffi is NOT installed
apt remove libffi-dev libffi6 libffi6-dbg

# Replace libffi-dev by liffcall1-dev
# in debian/control AND debian/templates/control.m4

# Edit debian debian/rules,
# in the override_dh_auto_configure target:
#
#dh_auto_configure -- \
#           ac_cv_lib_kvm_kvm_getenvv=no \
#            --disable-bfd \
#         --disable-libffi \
#            --enable-ffcall


# build package with default compiler

# Send me the Tests/tests.log file

2 -gcc-6 with libffcall1-dev

#rebuild package with gcc-6

# Send me the Tests/tests.log file

Thanks
