Description stompdagger1 2010-09-19 21:38:55 UTC
Application: kdevelop (4.0.2 (using KDevPlatform 1.0.2))
KDE Platform Version: 4.5.1 (KDE 4.5.1) (Compiled from sources)
Qt Version: 4.6.3
Operating System: Linux 2.6.35-gentoo-r7 x86_64
Distribution (Platform): Gentoo Packages

-- Information about the crash:
- What I was doing when the application crashed: starting up kdevelop. not much to add,
but the intresting thing is that when starting kdevelop from cli, it doesn't seems to crash.

The crash can be reproduced every time.

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

Comment 1 Milian Wolff 2010-09-25 23:27:06 UTC
is this still an issue? Somehow I doubt it's on our side if launching kdev from the CLI makes it work. That indicates some bug on your environment setup.

if you have more information showing it's a bug on our side after all, please reopen.

As said in one of the duplicates:

does it work when you properly set KDEDIRS and ran kbuildsycoca4 and launch
kdevelop through the command line? See duplicate bug and this howto:

http://www.kdevelop.org/mediawiki/index.php/KDevelop_4/compiling

If it pertains, please send me a valgrind log:

kdevelop --sessions # then find the {...hash...} for your session, now:
KDEV_SESSION={...hash...} valgrind --track-origins=yes --num-callers=25
kdevelop.bin

thanks

Also, please try to reproduce in KDevelop 4.1.
Comment 5 Mike Rublev 2010-10-22 17:51:10 UTC
I run it again started with new session from the CLI.
I'm just wondering, is it possible to remove KDevelop sessions? I have a huge list of them and I'd like to remove unused.

I've tried a fix for kdev 4.1.1 / 4.2, please - if anyone can test current code from git do so and report back. The commit was:

    try to fix crash in KDevelop::ConfigurableHighlightingColors::getAttribute
    
    - make sure m_defaultColors is always initialized
    - add assertion in getter
    
    This is just a shot in the dark but it might be the right one, see
    esp. the queued connection in update() which might have lead to periods
    without an initialized m_defaultColors member.

PS: a way to reproduce or a valgrind log from the crash would still be good.

It seems working by set KDEDIRS and kbuildsycoca4 :| but i've to test it for one or two day before to sing victory. 
It's strange, because when i install the binary package from archlinux official repository, kbuildsycoca4 seems not to start. :| boh!

if it persist i follow the steps below.

Thanks to you :)

What???? This bug is made by KDevelop 4.1 :), sorry but i have not understood what you are trying to say :)

kdevelop (4.1.0) on KDE Platform 4.5.2 (KDE 4.5.2) using Qt 4.7.0

- What I was doing when the application crashed:

Starting kdevelop. Was working in it yesterday, left few files open (no project), then shutdown comp.  After KDE login, kdevelop was launched and produced SIGSEG. After trying manually from KDE menu, SIGSEG again.

Valgrind log for the crashing kdevelop 4.1
Comment 13 Milian Wolff 2010-11-10 21:04:18 UTC
ok, I think the valgrind log you posted clarifies that I've fixed it. stay tuned for kdev 4.1.1

kdevelop (4.1.1) on KDE Platform 4.5.4 (KDE 4.5.4) using Qt 4.7.0

- What I was doing when the application crashed:
start kdevelop via synapse 

This is on Ubuntu 10.10 with ppa backports for KDE, kdevelop 4.1.1. So it's not fixed yet.

It exhibits the same behavior as reported above. Kdevelop crashes when launched via menu or gnome-do/synapse, but not from CLI

Comment 16 Ioannis 2010-12-18 17:26:22 UTC
starting via CLI with either 'setsid' or suffixed with '&', will cause the crash as well.
Comment 17 Milian Wolff 2010-12-19 19:36:22 UTC
please run it through valgrind then show me the log it produces when you hit the crash. Considering that it crashes somewhere else please put it into a new bug report. To run valgrind, use this:

valgrind --track-origins=yes --num-callers=25 kdevelop

thanks

valgrind log

crash from valgrind report (no debug symbols though)

I'll include the log produced by valgrind and the crash report for that here, even though the latter one has no debug symbols. Can't find them for my distro (Ubuntu). Added the ddebs as well for the dbgsym.
Comment 20 Milian Wolff 2010-12-20 20:00:47 UTC
Valgrind and gdb are mutually exclusive, the crash report is hence useless. And the memcheck log says KDevelop didn't crash, nor does it contain anything interesting. So please try again to actually reproduce the crash there, if you look at the log it doesn't say anything about KDevelop::CodeHighlightingInstance::highlightDUChain (which it should).

valgrind (memcheck) log

I see. Unfortunately that's all I get from memcheck. I'm including another produced log from valgrind, this time by streaming its output to a file (rather than using --log-file), including stderr. I don't get the KDevelop::CodeHighlightingInstance::highlightDUChain you mentioned, but you can see that kdevelop does crash.

kdevelop run without crashing log

don't know if that helps, but I've also added the output I get from kdevelop when run via CLI (without & or setsid), which doesn't crash.
Comment 23 Milian Wolff 2010-12-22 20:47:58 UTC
both are useless - I cannot help you without a way to reproduce (launching in the background with & or setsid both work for me). Anyways, this is unrelated to the original bug here - if you ever get more information, open a new bug. Just make sure you get a valgrind log that shows similar backtrace to the gdb crash, then you got something useful. The fact that this is not possible for you is really strange imo. Anyways, sorry - but nothing I can do.
