can you reproduce this in KDevelop 4.1 Beta 1?

and if you can, please run kdevelop through valgrind to show why it's failing:

valgrind --track-origins=yes --num-callers=50 kdevelop

(only works this way starting with kdevelop 4.1 or above)

configuration

first, sorry for such late reply

I've attached logs you asked for.
Crash is not reproducible with fresh configuration so I've attached configuration files that trigger crash.

I've also noticed that crash happens only when entering "Source Formater", browsing other settings is fine. That should narrow things a bit..


tested with
janc@athlon:~$ kdevelop --version
Qt: 4.7.2
KDE Development Platform: 4.5.3 (KDE 4.5.3)
KDevelop: 4.1.1

if you are still using kdevelop 4.0, first do an upgrade to 4.2 or at least 4.1 and see whether the crash is still there.

if it is, install debug symbols for kdevelop and reproduce the gdb + valgrind log as right now they are pretty useless.

thanks

fixed for 4.2.1 now, thanks for the logs Szymon.

If you want to patch 4.1 (which is not going to see future releases from us), just port the above patch to your branch. Should be straight forward.
