Summary0001529: xdebug_get_function_stack() wrong file, in frame calling __get() magic method
DescriptionThe wrong calling file is listed in a xdebug_get_function_stack() trace
file from previous frame appears to be listed
The correct line is shown
Steps To Reproducecall xdebug_get_function_stack() from within __get() magic method

attached file contains
index.php simply includes include.php
include.php calls ClassA::getInstance()-bogusProperty
ClassA __get method calls xdebug_get_function_stack()

produces this backtrace:

array (size=3)
  0 =>
    array (size=4)
      'function' => string '{main}' (length=6)
      'file' => string '/Users/bkent/Sites/xdebug_bug/index.php' (length=39)
      'line' => int 0
      'params' =>
        array (size=0)
          empty
  1 =>
    array (size=4)
      'file' => string '/Users/bkent/Sites/xdebug_bug/index.php' (length=39)
      'line' => int 22
      'params' =>
        array (size=0)
          empty
      'include_filename' => string '/Users/bkent/Sites/xdebug_bug/include.php' (length=41)
  2 =>
    array (size=6)
      'function' => string '__get' (length=5)
      'type' => string 'dynamic' (length=7)
      'class' => string 'ClassA' (length=6)
      'file' => string '/Users/bkent/Sites/xdebug_bug/index.php' (length=39)
      'line' => int 3
      'params' =>
        array (size=0)
          empty

The last frame has the correct line number, but the wrong file
the correct file is seen in stack[1]['include_filename']

This appears to be fixed in xdebug 2.6.0 (just tested with php 7.2)

As this is already fixed in Xdebug 2.6, there is nothing to do for me here. Thanks for reporting, and verification.
