Description bungeman 2013-10-23 01:15:09 UTC 
Application: kdevelop (4.5.60)
KDE Platform Version: 4.11.2
Qt Version: 4.8.4
Operating System: Linux 3.11.0-12-generic x86_64
Distribution: Ubuntu 13.10

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

Built kdevelop from git master at  218a87974d3a. Opened kdevelop project with cpp file open at startup. Once the file was parsed (showed up syntax hilighted) hovered over a macro (at its definition). The widget showing the macro information displays for a split second, and then kdevelop crashes. Commenting out line 99 of macronavigationcontext.cpp (delete m_widget) causes kdevelop to no longer crash in this situation (though probably causes a leak).  Perhaps the widget has already been destroyed elsewhere?

The crash can be reproduced every time.

-- Backtrace:
Application: KDevelop (kdevelop), signal: Segmentation fault

New crash information added by DrKonqi

kdevelop (4.5.60) on KDE Platform 4.11.2 using Qt 4.8.5

- What I was doing when the application crashed:
I didn't do much. I've opened a file, renamed a function, started compile to find out where it is used and bam, kdevelop crashed.

-- Backtrace (Reduced):

Comment 2 Milian Wolff 2013-10-24 12:35:47 UTC 
This seems to be new and more and more people hit it. We should investigate.

Guys, can you make sure that you properly rebuild everything after the recent API changes in kdevplatform? Not that this is some strange bug due to BIC?
Comment 3 Lukas Jirkovsky 2013-10-24 13:21:43 UTC 
I did a completely fresh build today, including the git clone. I have been able to hit it every time I hover over assert() macro.
Comment 4 Aleix Pol 2013-10-24 14:25:06 UTC 
I have it as well, I've been investigating and the bug is because AbstractNavigationContext is now  a QObject and KSharedObject, trying to figure out what's the exact problem.

Git commit a8859089ddac283ef0a3b2d886609cc4705e87ff by Aleix Pol.
Committed on 24/10/2013 at 15:53.
Pushed by apol into branch 'master'.

Make the AbstractNavigationContext a KShared instead of KSharedObject

Fixes crash when hovering a preprocessor macro, the tooltip destruction
would crash.

Comment 6 Christophe Marin 2013-10-28 10:48:22 UTC 
Aleix: The fix seems to break the kdev-control-flow-graph build
