Description:
------------
Throwing an exception within set_error_handler() produces an exception which produces a messed up backtrace. Each entry within the backtrace contains the 'args' for the previous call, with the most immediate entry missing its 'args'. In the case of my example below the string 'foobar' should be in the array 'args' for the call to B(), not A().

Reproduce code:
---------------
function handle_errors() {
	throw new ErrorException();
}

set_error_handler('handle_errors', E_ALL);

function A() {
	$foo->bar; // Purposely cause error
}

function B($c) {
	A();
}

try {
	B('foobar');
} catch (Exception $e) {
	var_dump($e->getTrace());
}

Expected result:
----------------
array(3) {
  [0]=>
  array(4) {
    ["file"]=>
    string(42) "/home/public/pdt/framework/html/error.php"
    ["line"]=>
    int(10)
    ["function"]=>
    string(13) "handle_errors"
    ["args"]=>
    array(0) {
    }
  }
  [1]=>
  array(4) {
    ["file"]=>
    string(42) "/home/public/pdt/framework/html/error.php"
    ["line"]=>
    int(14)
    ["function"]=>
    string(1) "A"
  }
  [2]=>
  array(3) {
    ["file"]=>
    string(42) "/home/public/pdt/framework/html/error.php"
    ["line"]=>
    int(18)
    ["function"]=>
    string(1) "B"
    ["args"]=>
    array(1) {
      [0]=>
      string(6) "foobar"
    }
  }
}
