 Visible warning appears when running 5.0.1 on PHP 7.1

 "Warning: array_merge(): Argument #2 is not an array in /[redacted]/wp-
 includes/load.php on line 63" error appeared on front end after autoupdate
 to 5.0.1.
 Error persistent on both themes twenty nineteen and twenty seventeen
 (although hidden behind the main image) with every plugin deactivated, and
 5.0.1 freshly reinstalled. When I changed PHP version to 7.2 the error
 went away. Back to 7.1.25 it reappeared.
