Summary0002085: Crash when used with source guardian encoded files
Description

When including files that are encoded with source guardian (https://www.sourceguardian.com/) I get a segmentation fault
This only happens when collecting coverage with filters set

Steps To Reproduce

First, you must be able to run files using the Source Guardian loaders. So install the loaders for your system
https://www.sourceguardian.com/loaders.html

Next, you'll need to encode a file with the Source Guardian encoder. You can sign up for a 14 day trial.
The file can be as simple as: echo "Hello World"; You can name it whatever you want, I named it encoded.php so the attached file has that as the file to include.

Next, execute the php file that's attached with the following command:
php -dxdebug.mode=coverage test1.php

I get the following:
Segmentation fault (core dumped)

It works fine on the non encoded version of the file
And if I take out the xdebug_set_filter call, it works fine on the encoded file.

I suspect that the issue has something to do with xdebug_set_filter

TagsNo tags attached.

xdebug_start_code_coverage(XDEBUG_CC_UNUSED);

require_once "encoded.php";

$coverage = xdebug_get_code_coverage();
xdebug_stop_code_coverage();
print_r($coverage);

Hi,

sorry, but I am not going to install software and closed binaries to fix a compatibility issue with a proprietary third party closed-source extension. If you want to have Xdebug work together with that, you're going to have to get them to provide a pull request to fix it.

cheers,
Derick

Hi Derick
No problem, I fully understand. However, I think I know where the issue is.
Can I submit a pull request? The reason I'm asking is that I doubt that they'll spend time fixing a piece of software that isn't theirs.

Certainly, have a look at the contributing guidelines at https://github.com/xdebug/xdebug/blob/master/CONTRIBUTING.rst, and let me know if you have questions.
