[PHP-BUG] Bug #51394 [NEW]: Error line reported incorrectly iif error handler throws an exception

From:             
Operating system: *
PHP version:      5.3SVN-2010-03-25 (SVN)
Package:          Scripting Engine problem
Bug Type:         Bug
Bug description:Error line reported incorrectly iif error handler throws an exception

Description:
------------
The test script code produces the following error:

[25-Mar-2010 13:25:29] PHP Fatal error:  Function name must be a string in
test.php on line 0

This is because there's actually two errors:
1. Undefined $empty notice
2. Function name must be string - fatal error

When error (1) is processed, due to the exception opline_ptr is set to the
exception handler opcode, so when the engine wants to report error (2) it
doesn't have proper opline_ptr to report the error. 

Test script:
---------------
<?php
function eh()
{
	throw new Exception("error!");
	return false;
}

set_error_handler("eh");
$a = $empty($b);

Expected result:
----------------
[25-Mar-2010 13:25:29] PHP Fatal error:  Function name must be a string in
test.php on line 9

Actual result:
--------------
[25-Mar-2010 13:25:29] PHP Fatal error:  Function name must be a string in
test.php on line 0
