Description

How to reproduce:

Take the files from the attachment and load the project in netbeans.
Put a breakpoint on the last line (the "echo $var;" line)
Click the "Debug Project" button in netbeans
I run this script from the command line like so: 

export XDEBUG_CONFIG="idekey=netbeans-xdebug"
php -d xdebug.remote_enable=1 index.php

Press the green "play" button.
Actual output "Socket Exception occured"
Expected output: not to get this error but to have normal debugging output.
Actual output in the console: Segmentation fault (core dumped)
Expected output in the console: "1"

 

Now look at line 3. Remove the & in front of $var to make the line look like this: 

$anon_function = function() use ($var)

Try this how to reproduce again.
Actual output: no error, everything works fine.
Actual output in the console: "0"

 Note: The xdebug.log is included in the tarball, as requested from the error dialog from netbeans.

 If you can't get the attachment from this issue:

Create a new netbeans php project (I choose "php project with existing sources").

Have this php script as index.php:

<?php
$var = 0;
$anon_function = function() use (&$var)
{
  $var++;
};
$anon_function();
echo $var;
