Error happens on Fedora 28 (golang-1.10.5-1.fc28.x86_64) and CentOS 7 (golang-1.11.2-3.el7.x86_64). Issue originally mentioned in https://github.com/ganto/copr-lxc3/issues/11#issuecomment-443419608

When running the test against the release tarball with manually compiled bundled libraries, the error cannot be reproduced:
