Bug ID: 357517
Summary: Crash in the background parser
Product: kdevelop
Version: 4.90.90
Platform: openSUSE RPMs
OS: Linux
Status: UNCONFIRMED
Keywords: drkonqi
Severity: crash
Priority: NOR
Component: general
Assignee: kdevelop-bugs-n...@kde.org
Reporter: cyrille.dun...@gmail.com
Application: kdevelop (4.90.90)
Qt Version: 5.5.1
Operating System: Linux 4.3.3-5.g008195a-default x86_64
Distribution: "openSUSE Leap 42.1 (x86_64)"
-- Information about the crash:
- What I was doing when the application crashed:
The application crashes when loading the project. It parses a number of files
before crashing but I have not been able to determine if it is a particular
file causing the crash. I suspect not, as it seems to be crashing at a random
point during the parsing.
The crash can be reproduced every time.
-- Backtrace:
Application: KDevelop (kdevelop), signal: Segmentation fault
Using host libthread_db library "/lib64/libthread_db.so.1".
