Description Eugen 2011-01-28 13:24:51 UTC 
Application: kdevelop (4.2.0)
KDE Platform Version: 4.6.00 (4.6.0)
Qt Version: 4.7.0
Operating System: Linux 2.6.35-24-generic x86_64
Distribution: Ubuntu 10.10

-- Information about the crash:
- Unusual behavior I noticed:
It seems like kdevelop is pretty sensible about the files it finds in the project directory. E.g. if it finds an aggregated JS / CSS file which are a bit larger by defintion, it crashes.

I finally started to exclude specific directories where those files are located, but still crashes are happen. Actually its that way for more then 6 months already, i just finally started reporting it.

Mostly crashes happen ( repeatedly ) while the project gets verfied / parsed. After excluding some directories it sometimes stops crashing.

My project is a PHP project ( Drupal ), middle-sized.

The crash can be reproduced every time.

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

Comment 1 Milian Wolff 2011-04-11 18:58:00 UTC 
for the record:

[19:01] <milian> ugh
[19:01] <milian> is it reproducible on start?
[19:01] <EugenMayer> AFAIK i remember it even happend on my kde 4.5 installation ( a completly fresh installation ) ~5 months ago when i tried KDE once again
[19:01] <milian> i.e.: can you run it through valgrind?
[19:02] <EugenMayer> and finaly gone back to gnome again due the whole pim-stuff :/
[19:02] <EugenMayer> milian: hmm, currenlty it does not crash.
[19:02] <EugenMayer> valgrind ~ kcachgrind?
[19:02] <milian> also: when it crashes - do you see anything on the cli?
[19:02] <milian> like an out-of-memory assert
[19:03] <milian> EugenMayer: if you ever reproduce it run kdev like this "valgrind --track-origins=yes --num-callers=25 kdevelop"
[19:03] <EugenMayer> hmm, i cant really remember. when it crashes on the next project, i will try to check the cli

and: if you find a way to reproduce, please tell me what project it is (i.e. if possible send me a tarball)
