Example file for crash background parser

SUMMARY
KDevelop crashes while background parsing my files of the project (since updating from 5.2.4 to 5.2.80)

Thread 17 "Queue(0x5555563" received signal SIGSEGV, Segmentation fault.
[Switching to Thread 0x7fffa6286700 (LWP 9521)]
Php::ExpressionVisitor::visitStaticMember (this=0x7fffa62816b0, node=0x7fff8e16ce80) at /home/opitz/kde/src/extragear/kdevelop/plugins/kdev-php/parser/php.g:870

Compiled from git-master with debugging information and with help from IRC channel I dragged this down to one line out of Symfony package.

> $ ./duchainify -r ~/projects/vendor/symfony/debug/DebugClassLoader.php

The line in question is: > self::${$annotation}[$name] = '';<

Comment 2 Francis Herne 2018-10-25 15:23:07 UTC 
Reproducible with current 5.3-git. A file containing only '<?php' and the mentioned line causes an immediate crash when parsed.

Pasting backtrace inline for better SEO:

Comment 4 João Ferreira 2018-11-02 16:06:31 UTC 
Created attachment 116055 [details]
New crash information added by DrKonqi

kdevelop (5.3.0) using Qt 5.11.2

- What I was doing when the application crashed:

Just launched the application and browsed some open tabs; KDevelop will crash by itself after a few seconds. My PHP project is also using Symfony.
