[ganto]

When building lxd.spec with release 3.6 or later, the go test of github.com/lxc/lxd/shared/generate/db aborts with:

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 #11 (comment)

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