Summary0001503: Undefined Property error on CLI when inspecting private property of extended class.

When inspecting a private property on a parent class, an internal error is reported on the CLI, though the inspection still works.

Produced using xdebug 2.6.0dev on Php 7.2.0 (CentOs) with PhpStorm 2017.3.1 (Windows 10)

Steps To Reproduce

See attached file.

  1. Add a Breakpoint on $x
  2. Run php test.php
  3. inspect $b
  4. inspect $b->data2
  5. inspect $b->Adata1

Error is produced in step 5. Step 4 is optional.

Observed outcome:

$ php test.php
PHP Notice: Undefined property: B::$Adata1 in /var/www/tms/test.php on line 27
PHP Stack trace:
PHP 1. {main}() /var/www/tms/test.php:0

Notice: Undefined property: B::$Adata1 in /var/www/tms/test.php on line 27

Call Stack:
0.0069 388184 1. {main}() /var/www/tms/test.php:0

Additional Information

Reproduced while trying to further diagnose issue 0001335 (which is also occurring for me with this arrangement)

Note it says "v2.6.0dev" only because I customised the version string to ensure it was actually using the compiled version, rather than the most recent "v.2.6.0alpha1" pre-compiled module.
