Description

Environment:

Fast-CGI
PHP 8.1.30

The php-cgi process crashes with this information in the event log:

I setup debug symbols and compiled xdebug myself to get a pdb file.
The stacktrace to the exception is:

It seems the executed_filename variable contains an invalid value, see the attached screenshot of Visual Studio.

Debugging PHP or any other native code is new to me. As you can see, I've got it setup pretty well, so if you need any more information please let me know how I can help.

I think it's the same issue as https://bugs.xdebug.org/view.php?id=2229 — but I've not managed to nail down the problem here.
