I can't reproduce this. When I run this script with PHP 7.4 as CLI, I
only get the expected result:

PHP Fatal error:  Uncaught Error: Call to undefined function xxx() in
D:\test-errorhandler.php:11
Stack trace:
#0 {main}
  thrown in D:\test-errorhandler.php on line 11

Do you run the above script within a larger application which already
has some kind of error handling in place?
