Summary0000348: Wrong count of code coverage dead code (not executed lines) with Xdebug 2.0.2
Description

I've 4 Gentoo servers, all have the same configuration.

I've isolated the test with only 2 PHP files :

toto.php :
<?

class bobi {
function bordel() {
echo 'ah';

// hop

    echo "toto";

}
}
?>

And cover.php :
<?
xdebug_start_code_coverage(XDEBUG_CC_UNUSED | XDEBUG_CC_DEAD_CODE);

require_once 'toto.php';

print_r(xdebug_get_code_coverage());
xdebug_stop_code_coverage();
//phpinfo();
die();
?>

When i try :
php ./cover.php

I've this result on 3 servers :
Array
(
[/home/user/toto.php] => Array
(
[3] => 1
[5] => -1
[9] => -1
[10] => -1
[14] => 1
)

[/home/user/cover.php] => Array
    (
        [4] => 1
        [6] => 1
    )

)

But on the fourth i've a wrong result :
Array
(
[/home/user/toto.php] => Array
(
[3] => 1
[13] => 1
)

[/home/user/cover.php] => Array
    (
        [4] => 1
        [6] => 1
    )

)

Additional Information

All servers are gentoo, with this compile args for php :

Here are the php versions of the 3 good servers :
PHP 5.2.5-pl1-gentoo (cli) (built: Dec 29 2007 15:26:08)
Copyright (c) 1997-2007 The PHP Group
Zend Engine v2.2.0, Copyright (c) 1998-2007 Zend Technologies
with Xdebug v2.0.2, Copyright (c) 2002-2007, by Derick Rethans

And here is the "php -v" for the bad server :
PHP 5.2.5-pl1-gentoo (cli) (built: Jan 14 2008 23:17:29)
Copyright (c) 1997-2007 The PHP Group
Zend Engine v2.2.0, Copyright (c) 1998-2007 Zend Technologies
with Xdebug v2.0.2, Copyright (c) 2002-2007, by Derick Rethans
in xdebug_profiler_output_aggr_data() with 0 entries

Note the last line above... I think it's a weird bug isn't it ?
Anyone can explain a bug in "php -v" ???

I can't reproduce, I get the correct output. I can only image that there must be something different with the 4th server. Perhaps you've some sort of optimizer loaded?
