@cmb's examples work fine as of PHP 7.4. Is there anything else left to do here?

I can reproduce the described behavior (as of PHP 5.3.18
respectively 5.4.8), see <https://3v4l.org/U9bu8>.
Interestingly,
silencing the require statement results in no message at all, see
<https://3v4l.org/N42dN>.

There seem to be more problems with internally generated errors, as the following testcase
demonstrates:

<?php

set_exception_handler(
    function(Exception $e){ 
        echo "-- handler --\n"; var_dump($e); exit(1);
    }
);
set_error_handler(
    function($severity, $message, $file, $line) { 
        throw new ErrorException($message, 0, $severity, $file, $line); 
    }
);

try {
    require 'non-existing-file.php';
} catch (\Exception $e) {
    echo "-- catch --\n";
    var_dump($e); exit(2);
}


Expected result:
Either a "classical" Fatal Error should occur or the warning for the missing file should
be converted into an exception which in turn should be caught by catch() or at least by the global
exception handler.


Actual result:
theseer@nyda ~/Desktop/Error $ php -v

The same behavior can be observed with my (relatively old) PHP 7 build:

theseer@nyda ~/Desktop/Error $ php70 -v

Hey laruence,

Sorry for the typo, I was copying the code from my real project. Should have ran it. That said,
corrected the typo and it is still behaving exactly the same:

Fatal error: Uncaught exception 'Exception' with message 'Hello world' in
/Projects/web/test/bug.php on line 3

So far I've tested this on a machine running Mac OS X 10.8.6 and one running Windows (2012
server I think).
