Switching to the PPA ppa:ubuntu-toolchain-r/ppa fixes this for Bionic, since there is no gcc-10 there and this issue does not occur. That repo does however not contain GCC-9 for Xenial, and most of Travis-CI jobs still run on Xenial (their default distro at the moment), so recommending everybody to switch to the ppa:ubuntu-toolchain-r/ppa is not a full solution.
I think this bug report should however be kept open as a note for gcc-10 packagers, who might want to study this conflict on s390x. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1872854 Title: GCC-10 library conflict on s390x To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/gcc-10/+bug/1872854/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
