@pitrou I cannot reproduce core dump here on Ubuntu 16.04 with Python versions 3.6.6 nor 3.7.0.
However, I suspect that the core dump could be related to the usage `manager.free_host(buf)` in `test_manage_allocate_free_host`. Could you try commenting out the calls to `free_host` method and rerun the tests?
