Sorry for sloppy bug report. Here are exact steps to reproduce on a
Ubuntu 18.04 host (arch amd64) running s390x in a Docker container. The
bug is not repeatable on amd64 since the s390x packages available on
Bionic is slightly different.
# Install s390x emulators
sudo apt install qemu-user-static qemu-system-s390x
# Enable experimental mode in Docker
cat /etc/docker/daemon.json
{
"experimental": true
}
sudo systemctl restart docker
# Pull s390x Bionic
docker pull --platform linux/s390x ubuntu:bionic
# Prepare and build container
mkdir s390x; cd s390x
cp /usr/bin/qemu-s390x-static .
cat Dockerfile
FROM ubuntu:bionic
COPY ./qemu-s390x-static /usr/bin/qemu-s390x-static
RUN uname -a
RUN apt-get update -y && \
apt-get install --yes --no-install-suggests --no-install-recommends
software-properties-common curl gpg gpg-agent dirmngr ca-certificates && \
echo 'deb http://ppa.launchpad.net/ubuntu-toolchain-r/test/ubuntu bionic
main' >> /etc/apt/sources.list.d/toolchain.list && \
apt-key adv --keyserver keyserver.ubuntu.com --recv

apt-get update -y
RUN apt-get --no-install-suggests --no-install-recommends install clang-7
clang-8 g++-5 g++-7 g++-8 g++-9
# Run
docker build --tag ubuntu:bionic-s390x .
