OpenSSL 1.1.1c is out, https://github.com/openssl/openssl/blob/OpenSSL_1_1_1c/CHANGES

test_start_tls_server_1 is failing reproducible with OpenSSL 1.1.1c on Linux (Fedora 29).

Ah, thanks! I forgot about that bug.

The test suite is aready failing with OpenSSL 1.1.1b.

Also those failures are recorded on the Fedora buildbot, it seems to be happening randomly: https://buildbot.python.org/all/#/workers/32

Should we update the Windows and Mac installers to 1.1.1c now?
