Description Alexey Chernov 2014-08-15 07:19:07 UTC 
- What I was doing when the application crashed:

KDevelop crashed on some early stage of startup. It was closed correctly before. I think I can't reproduce it another time as it's the very first time I see this crash for a long time.

-- Backtrace:
Application: KDevelop (kdevelop), signal: Aborted

Comment 1 Milian Wolff 2015-11-01 19:12:20 UTC 
Hello!

We are working on a new clang-based C/C++ language plugin for KDevelop 5 which supersedes the old C++ plugin in KDevelop 4. See e.g.: https://www.kdevelop.org/news/first-beta-release-kdevelop-500-available

Due to a lack of manpower, we cannot fix bugs in the old C++ plugin. We rather want to supply a good Clang based C++ experience for KDevelop 4 than wasting our time on the legacy C++ support for KDevelop 4. For that reason, I'll close this bug. Please stay tuned for KDevelop 5.

If you think that this bug also affects KDevelop 5 with Clang, feel free to reopen the report!

Sorry for the inconvenience, I hope you understand the reasoning above.

Cheers
Comment 2 Alexey Chernov 2015-11-01 19:20:36 UTC 
Yes, no problem. I fully agree with switching full focus to version 5 and also plan to switch to already released beta of it to possibly help a little with reports if any bugs would appear there.

Thank you very much for detailed description of the decision and good luck with the new version!
