Description Romek 2011-06-15 11:44:41 UTC 
Application: kdevelop (4.2.60)
KDE Platform Version: 4.6.2 (4.6.2) (Compiled from sources)
Qt Version: 4.7.2
Operating System: Linux 2.6.38-8-generic-pae i686
Distribution: Linux Mint 11 Katya

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

Every time I try to find uses of following typedef the kdevelop crashes:

typedef SomeType (*TraversalCallback)(TheOtherType* pObjPtr,
                                           JustAnotherClass* pTcPtr, 
                                           void* pUserData);

So basicaly after pressing right mouse button on TraversalCallback word and selected Find Uses, the app crashes.

I have had opened 3 projects and they have quite lot of files.

If you need more details please contact me.

BR,
Roman

The crash can be reproduced every time.

Comment 1 Romek 2011-06-15 11:50:42 UTC 
I have reproduced it even in very small project - one file with simple callback declaration like:

template<class T>
struct Callbacks
{
    typedef void (*myCallback)(T);
};

Trying to find uses of myCallback cause a kdevelop crash.

Comment 3 Milian Wolff 2011-06-17 23:37:04 UTC 
note that you still won't get proper uses for this one, as function pointers are still not properly handled by the cpp parser (bug report exists for that afair)...

please stay tuned

ups, closing again
