You may have noticed that we sometimes get a test failure from this test: test_ssl_missing_client_certificate
When that happens, the returned error is SERF_ERROR_ISSUE_IN_TESTSUITE. I've been trying to track this down for a while now. It happens on both Linux and macOS, but only with OpenSSL 1.0.x; I've never seen that failure with OpenSSL 1.1.x. >From all I've seen in a myriad debugging sessions, it appears that there's a memory corruption bug within OpenSSL itself. Can anyone please try to confirm that? I have not seen this test failure on Windows, but I also haven't tested on that platform very often. -- Brane
