Description anikulin 2013-03-20 07:54:08 UTC

Application: kdevelop (4.3.1)
KDE Platform Version: 4.8.4 (4.8.4)
Qt Version: 4.8.2
Operating System: Linux 3.2.0-4-amd64 x86_64
Distribution: Debian GNU/Linux 7.0 (wheezy)

-- Information about the crash:
I was waiting for breakpoint hit while debugging application. It causes by incoming nertwork packet. Packet come and crash occured instead of hit.

I use sudo gdb, because of 53 port and /var/lib usage.

The crash can be reproduced some of the time.

-- Backtrace:
Application: KDevelop (kdevelop), signal: Aborted
Using host libthread_db library "/lib/x86_64-linux-gnu/libthread_db.so.1".

This looks like an upstream bug. Crash in Qt style, nothing we can do about.

Comment 2 Christoph Feck 2013-04-24 10:01:23 UTC

It says "malloc(): smallbin double linked list corrupted". The memory corruption could have happened anywhere before the application called into QStyle.

If this is reproducible, please try generating a valgrind log. For more information, see http://techbase.kde.org/Development/Tutorials/Debugging/How_to_create_useful_crash_reports#Retrieving_a_backtrace_with_Valgrind
