OS: macOS 10.12.6
Affected google-cloud-storage versions: 1.1.1 and 1.3.2
Python version: 3.6.2 (conda venv)

For v1.1.1:
Using Python's multiprocessing library to spawn a child process (via Process), the google-cloud-storage library seems to fail when calling blobl.download_to_filename(...). I don't get any error message, but the exitcode of the process is -11.

For v1.3.2
Under the same conditions, storage_client.get_bucket(bucket_name) seems to fail without an error and the process has the same exitcode of -11.

The process I'm spawning isn't daemonic. Let me know if there's any additional info I can provide. I can't really give any code snippets, and I haven't yet been able to extract any additional traceback/error info.
