Summary0002241: Segmentation fault - Symfony 6.2.1 - Sulu cms
Description

There is error, even after trying to deep dive into functions I was not able to find specific php function, when there is presented breakpoint (on any line of code that is after this function) the xdebug will crash

Steps To Reproduce

(this was tested only in phpstorm)

  • Set breakpoint inside file Sulu\Bundle\WebsiteBundle\Controller\DefaultController on first line inside indexAction ($response = $this->renderStructure...)
  • Open homepage
  • Make step over or resume program
  • Segment fault
Additional Information

This only occurrences when the breakpoint is pressented, when I remove the breakpoint and resume the apllication (even if I already landed on breakpoint) the Segment fault did not occurrences.

Also from time to time (this is not always possible to reproduce), the segment fault occurrences also when the breakpoint is set to disable.

I was trying to deep dive into specific line that is casing this error, because this step is online call on Sulu function renderStructure, but after lot of step into steps I did not managed to find it.
