Xdebug has detected a possible infinite loop - problem with latest, not with 3.4.1

[oleibman]

We issued a new release and the documentation was generated without a problem. I believe the install used phpDocumentor 3.4.1 to generate the documentation. I realized that my local version was long out of date, so I downloaded the latest phar version (3.4.3), and this did report a problem (so the problem seems to have been introduced by 3.4.2 or 3.4.3):

[alert]   Unable to parse file "PhpSpreadsheet/src/PhpSpreadsheet/Writer/Xlsx/FunctionPrefix.php", an error was detected: Xdebug has detected a possible infinite loop, and aborted your script with a stack depth of '256' frames

Expected behavior

Produce documentation for all members including FunctionPrefix.php.

Actual behavior

Documentation is produced for all members except FunctionPrefix.php, which instead outputs the error message above.

Steps to reproduce the problem

1. php phpDocumentor.phar run -d PhpSpreadsheet/src/PhpSpreadsheet/Writer/Xlsx/FunctionPrefix.php -t docs

Your environment

• Version used: 3.4.3
• Install method: Download phar from your releases page
• PHP version 8.1.26
• Operating system and version (e.g. Ubuntu 20.04, Windows 10): Windows 11
• Link to your project: https://github.com/PHPOffice/PhpSpreadsheet
• Attach code that is involved
• ...
  FunctionPrefix.zip

We moved away from a cached service container because we are working on support for extensions. I expect this is the causing the issue.

Raising the value on xdebug will solve this issue as the service container has more nesting than 256 layers.

Sorry to be obtuse - raising what value on xdebug?

This is most-likely causing the issue/

Thank you. Before I had received your reply, I tried php -d xdebug.mode=off ..., and that eliminated the error. This was needed locally for 3.4.3, but also for 3.4.1 (so my initial report that 3.4.1 was okay was wrong). I will keep your suggestion on nesting level in mind, but, for now, this will do.
