Comment 1 Martin Flaska 2013-09-04 05:44:01 UTC

Maybe duplicate of bug 307172. I opened larger C++ project, then after 1-2 minute I closed kdevelop, so it crashed after that. I am not sure whether was the background parser still active.

valgrind log

Now this is reproducible every time I run/exit kdevelop. I am attaching valgrind log, maybe it will be helpful. 

I have closed kdevelop after background parser finished.

valgrind --track-origins=yes kdevelop

kdevelop (4.5.1) on KDE Platform 4.11.1 using Qt 4.8.4

- What I was doing when the application crashed:

I was exiting KDevelop. Immediately before, I had saved my last modifications to a C++ project.

Comment 4 Aleix Pol 2013-09-20 17:52:09 UTC

I haven't seen this problem, maybe it was fixed in further versions? I'd recommend you to upgrade to a newer version.

kdevelop (4.4.1) on KDE Platform 4.10.5 using Qt 4.8.4

- What I was doing when the application crashed:
exiting KDevelop. Opened large C++ project, no interaction with UI (compilation, ...), only checkouted anther commit (Git) in the same branch. I am not sure whether was the background parser still active.

This happen quite often, even if I do not touch source code (git checkout, or another text editor, whilst kdevelop is run)
