Description Matthijs 2017-06-12 11:02:18 UTC 
Application: kdevelop (5.1.1)

Qt Version: 5.9.0
Frameworks Version: 5.35.0
Operating System: Linux 4.11.3-1-ARCH x86_64
Distribution (Platform): Archlinux Packages

-- Information about the crash:
- What I was doing when the application crashed:

When I start Kdevelop (either with or without cleared cache), it starts parsing the php project (using Symfony). At some point it crashes, although I do not know which file(s) cause the problem. Before that moment, everything works fine, except for some code completion since the project is not fully parsed yet.

If more debug symbols are needed, let me know, I'll recompile some packages.

The crash can be reproduced every time.

-- Backtrace:
Application: KDevelop (kdevelop), signal: Segmentation fault
Using host libthread_db library "/usr/lib/libthread_db.so.1".
