Comment (by t0nnyh0ang):

 Replying to [ticket:37122 kraftbj]:
 > When PHP XML is not available, we fatal with an `PHP Fatal error: Call
 to undefined function xml_parser_create()` in `wp-includes/class-IXR.php`
 and other files.
 >
 > We already error out when that function is not available in `wp-
 includes/rss.php` since [3083].
 >
 > Background: The PHP 7 packages on Ubuntu, unlike PHP 5, does not include
 `php7.0-xml` by default, so there may be an increase in failures of this
 type as folks switch over.
