Summary0001760: xdebug appears the line that's not exist at all
Description

i'm using xdebug to collect coverage data from a web framework CodeIgniter ,but somethind weird happen, the coverage data contains lines that the file could never have, like the autoload.php

<pre>
<?php

// autoload.php @generated by Composer

require_once DIR . '/composer/autoload_real.php';

return ComposerAutoloaderInitb2b31c9dfea89a8b6a59f8b59f651b1a::getLoader();
</pre>

and the coverage data is this:

"share/php/framework/system/vendor/autoload.php":{"5":1,"7":1,"8":-2,"23":1}

the file autload.php only has 8 line ,so line 23 comes out of where?

and the 23 can always appear with specific request

i'mt sorry that the php framework code is too large to bring out and i cant give a small sample file to test

Xdebug 2.5 is no longer supported (https://xdebug.org/docs/compat) and neither is PHP 5.6 (https://www.php.net/supported-versions.php). If you can reproduce this problem with supported versions, then please update this report with a full self-contained example, with all steps required for me to reproduce this problem. Without this, I can not investigate, and hence, attempt to fix this problem.

cheers,
Derick

i provide a sample project here, you can unzip it
and run by this:

cd vendor
php autoload.php

the running result in my environment is :
'/root/phpok/vendor/autoload.php' =>
array(4) {
[5] =>
int(1)
[7] =>
int(1)
[8] =>
int(1)
[23] =>
int(1)
}
'/root/phpok/vendor/composer/ClassLoader.php' =>
array(5) {
[44] =>
int(1)
[302] =>
int(1)
[303] =>
int(1)
[442] =>
int(1)
[446] =>
int(1)
}

hope that i can help you to reproduce this problem

Please upgrade PHP to a supported version.

i'm afraid upgrading an old system is not so easy,

so the bug is in xdebug or in php internals?

if in xdebug, i may try to fix it

if in php internal, then i'll leave it alone
