Description keithwilliams333 2018-01-16 12:45:45 UTC 
Application: kdevelop (5.2.1)

Qt Version: 5.10.0
Frameworks Version: 5.42.0
Operating System: Linux 4.14.13-1-ARCH x86_64
Distribution: "Arch Linux"

-- Information about the crash:
kdevelop crashed while editing a file.  I restarted, using the existing cache as I wanted to recover my changes.  I was able to save changes, but every time I  pressed a key when one particular file was in view, it crashed. 

The session was initially started from a newly created project from an existing makefile.

Using ArchiLinux distribution of Kdevelop 5.

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".

Without clearing the cache, I did the following:
1. open kdevelop
2. close the file tab of the offending file
3. reload the project, it was closed
4. opened the file again
5. refuse to recover the file, all changes were lost
6. apply changes again

kdevelop did not crash again.  The error seems to be handling that one file.
Comment 2 Kevin Funk 2018-01-16 13:04:54 UTC 
Can you share the offending file? Can you remove as much content of the file as possible while KDevelop still crashes (reducing the test case)?

That would help a lot!
Comment 3 keithwilliams333 2018-01-16 15:00:06 UTC 
Created attachment 109912 [details]
The offending file (as requested).

Once I removed the file from kdevelop and opened it again it was fine.

I don't know if the problem was related to creating a new kdevelop project from an existing makefile, and then using that session to edit the file.  It could be some bad state inherited from that.
