Interruption due to regression in Safari Technology Preview #609

Safari Technology Preview version 66 was released yesterday (2018-09-26), and the subsequent collection attempt failed. The build error occurs while attempting to enable remote automation. It can be reproduced by attempting to run SafariDriver, e.g.

"/Applications/Safari Technology" --port 9876

That command is expected to start a WebDriver server. In Safari Technology Preveiw version 66, it immediately fails with an exit code of 1. No information is printed to standard ouput or standard error, but the following logging messages are available in the macOS "Console" application:

I've recently been expecimenting with collecting results from the stable release of Safari (in service of gh-604), so I initially suspected that may be the cause of the problem. However, after uninstalling version 66 and installing 65, the command referenced above operates as expected.

@burg Would you mind reporting this in WebKit's internal issue tracker? I've generated a system report using sysdiagnose--let me know if you'd like me to e-mail it to you.

Brian has confirmed the issue, and a fix is on the way.

In the mean time, I'll see what I can do about hard-coding this project to use Safari Technology Preview version 65.
