Bug description: preg_replace_callback swallows exceptions
Description:
------------
If a function called by preg_replace_callback throws an
exception this exception is not propagated up to the
function which called preg_replace_callback. Instead a PHP
error is produced. This error contains no information about
what the problem was or where it occurred.
Reproduce code:
---------------
<?php
function thrower() {
throw new Exception("Hello");
}
try {
$b = preg_replace_callback('/./', 'thrower', 'a');
} catch ( Exception $e ) {
echo 'Yay, exception!';
}
?>
Expected result:
----------------
code to output
Yay, exception!
Actual result:
--------------
Warning: preg_replace_callback(): Unable to call custom
replacement function on line 13
