This is actually a duplicate of #851, and the underlying cause of this is that your library is being compiled normally and with --test. The normal compilation is happening because it's necessary to run doctests afterwards.

You can specify doctest = false for now and we'll eventually add more CLI flags to control which tests are run to only build one. For now though this is working as intended.
