Description Jinx 2011-12-04 10:36:13 UTC 
Application: kdevelop (4.2.3)
KDE Platform Version: 4.7.2 (4.7.2)
Qt Version: 4.7.4
Operating System: Linux 3.0.0-13-generic i686
Distribution: Ubuntu 11.10

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

I was trying to build from a basic welcome tutorial in C#.

copied and pasted below

// Namespace Declaration
using System;

// Program start class
class NamedWelcome
{
    // Main begins program execution.
    static void Main(string[] args)
    {
        // Write to console
        Console.WriteLine("Hello, {0}!", args[0]);
        Console.WriteLine("Welcome to the C# Station Tutorial!"); 
    }
}

This is the first build I've attempted in KDevelop.

New crash information added by DrKonqi

kdevelop (4.2.3) on KDE Platform 4.7.3 (4.7.3) using Qt 4.7.4

- What I was doing when the application crashed:
Tried to build a test file when the crash happened.
I was testing a bug report example (bug 288251) when the crash occured.
The same test doesn't crash in QtCreator 2.3.1

Comment 2 Myriam Schweingruber 2011-12-07 16:54:31 UTC 
Confirmed by duplicate.
Comment 3 pclausen 2012-03-08 01:36:33 UTC 
I can only reproduce this - but only sometimes - presing the build button causes a seg-fault / crash. I was trying to build a large cmake project that have already compiled succesfully a couple times in th open session, then sometimes this crash.

Info (built on ubuntu 10.04 64-bit):

Qt: 4.7.0

Comment 4 pclausen 2012-03-08 13:22:18 UTC 
it happened again after many successful builds, but right after I did a quite large update of files using source control (outside kdevelop). 

@Jinx: Did it crash for you in a similar manner ?
Comment 5 pclausen 2012-03-09 12:21:45 UTC 
This happens quite often and is very annoying. If I can somehow give more information about this problem that could help solving it I will be happy to supply it.
Comment 6 Milian Wolff 2012-03-09 12:35:05 UTC 
without a way to reliably reproduce this issue, it's simply tough or nearly impossible to fix I'm afraid...
Comment 7 pclausen 2012-03-10 17:38:30 UTC 
Created attachment 69464 [details]
newest back trace
Comment 8 pclausen 2012-03-10 17:43:34 UTC 
The problem is I cant reproduce it as such. I have a couple of successfull builds (<10) using just compiled kdevplatform and kdevelop using latest sources (git pull in both directories from today, 10.3.2012). And now it happend again, see newest back trace in the previous "comment" from me.

If you have any ideas or hints to get better infomation about what is going wrong, I'll be happy to try it out. Should I make a debug build? Will that give me more info? Can I call kdevelop in a special way to start it in a debugger when an exception is thrown?
Comment 9 Andreas Pakulat 2012-03-27 12:58:38 UTC 
@pclausen: Please open a new report, your backtrace clearly shows you're running into some other problem than the original two reporters.

For the original reporters: the backtraces do not match current code and against the 4.2.3 codebase such a crash report suggest some bad memory-corruption happening. For this a valgrind report is necessary. So if this is still reproducable with KDevelop 4.3, please provide a valgrind log of the crash.
Comment 10 pclausen 2012-03-28 20:19:43 UTC 
@Pakulat: OK, and thanks for looking into this. I'm away from my main working station the next 4 weeks, so please be patient. :-) When I get back I'll open a new bug as you suggested with backtrace. If you need a valgrind report, please point me to a documentation how to do so...
