Summary0002343: Fatal error on virtual property hook step debugging
Description

Attempting to step debug any line within a PHP 8.4 virtual property block causes Xdebug to respond with a Fatal error.

Steps To Reproduce
  1. Load the attached example file: example.php
  2. Start step debugging on line 8 in the example file (the return statement)
  3. Xdebug will respond with an Error
Additional Information

Any line step debugged within a property hook/accessor block will cause this issue. It also seems to block further execution of the PHP script but that might be down to my setup so I'm not sure. Running my example script without Xdebug will echo the current date as expected.
