Description:
------------
In PHP 7.2, if a error is triggered while using reflection to inspect an object,
and a error_handler is set as a method of a class, the error handler object
cannot access its own private attributes.

Short (about 60 lines) and example of the code with comments is here https://gist.github.com/juan-leon/0c33d86b1bda88b6281fdcf451dc1192

Example code is working for PHP 7.0, and its output is in the expected results section.

Example code is failing for PHP 7.2, and its output is in the expected results section (notice the Fatal Error description)





Test script:
---------------
https://gist.github.com/juan-leon/0c33d86b1bda88b6281fdcf451dc1192

Expected result:
----------------
property dummy1 value is 1
Dealing with error Undefined property: Foo::$dummy2, /home/bb1/www/weird_error5.php, 57
Never executed in PHP7.2; there is a fatal error in the line above
property dummy2 value is 
This line is not reached in PHP7.2; but it is reached in PHP 7.0


Actual result:
--------------
property dummy1 value is 1
Dealing with error Undefined property: Foo::$dummy2, /home/bb1/www/weird_error5.php, 57
