--- Comment #1 from Dan Horák dan@danny.cz --- So it's not golang, but binutils, there is no error with binutils-2.28-2.fc27.s390x and the issue was introduced with http://pkgs.fedoraproject.org/cgit/rpms/binutils.git/commit/?id=416e01445516...
And it's most likely a dupe of #1442023 with much smaller reproducer.
