Sentry Crash Report:

Description Cyrille Dunant 2016-01-04 14:28:31 UTC 
Application: kdevelop (4.90.90)

Qt Version: 5.5.1
Operating System: Linux 4.3.3-5.g008195a-default x86_64
Distribution: "openSUSE Leap 42.1 (x86_64)"

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

The application crashes when loading the project. It parses a number of files before crashing but I have not been able to determine if it is a particular file causing the crash. I suspect not, as it seems to be crashing at a random point during the parsing.

The crash can be reproduced every time.

-- Backtrace:
Application: KDevelop (kdevelop), signal: Segmentation fault
Using host libthread_db library "/lib64/libthread_db.so.1".

^ This is indicates the problem is the KDevelop PHP support plugin, FWIW.
Comment 2 Cyrille Dunant 2016-01-04 14:50:41 UTC 
I uninstalled the PHP plugin, and the crash disappeared. It may be that trying to parse the pure c++ project I loaded had side effects...
Comment 3 Milian Wolff 2016-01-04 15:31:14 UTC 
The PHP plugin tries to parse the builtin PHP function file when KDevelop gets loaded, which may have lead to the crash above. I'd still be interested in seeing a proper backtrace for this crash, or a way to reproduce it.
Comment 4 Cyrille Dunant 2016-01-04 15:39:50 UTC 
There is your (hopefully correct) trace
