Severity: crash
Priority: NOR
Component: general
Assignee: kdevelop-bugs-n...@kde.org
Reporter: akim...@gmail.com
Target Milestone: ---
Application: kdevelop (5.10.221202 (22.12.2))
Qt Version: 5.15.8
Frameworks Version: 5.103.0
Operating System: Linux 6.1.0-25-amd64 x86_64

DrKonqi: 5.27.5 [KCrashBackend]
-- Information about the crash:
KDevelop spontaneously crashes, presumably in process of parsing my files
(C++). This belief of mine is due to the fact that crashes seem unrelated to
any particular user action -- sometimes there was no action at all, at the
moment of crash.
I utilize mixed templating+virtual functions and multiple inheritance; this
confuses a lot of parsers.
Sometimes, KDevelop itself just refuses to update its warning/error highlight
or text suggestions in some file, until an error in another file (not
necessarily directly relevant to said file) is resolved. I believe, other times
this results in a crash.
The crash can be reproduced sometimes.
