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

This bug exists under 5.2.1/win. I saw it here first as a bug under 5.2.1/debian and there it said the bug would is gone in 5.2.1 but under win it's definetly not.

Just get the latest XAMPP, install it under win and run the code. The line 13/14 is just because i copied the code from the other bug report since it's the same.

What kind of bug? The exception is thrown and successfully caught.
I agree that the warning is not needed in this case, I'll discuss it with the extension maintainer.
