Bug ID: 493410
Summary: crash from consecutive `ctrl+.` definition navigations
of functions/structures/variables
Classification: Applications
Product: kdevelop
Version: unspecified
Platform: Ubuntu
OS: Linux
Status: REPORTED
Keywords: drkonqi
Severity: crash
Priority: NOR
Component: general
Assignee: kdevelop-bugs-n...@kde.org
Reporter: j...@advops.com
Target Milestone: ---
Application: kdevelop (5.12.230805 (23.08.5))
Qt Version: 5.15.13
Frameworks Version: 5.115.0
Operating System: Linux 6.8.0-45-generic x86_64

Distribution: Ubuntu 24.04.1 LTS
DrKonqi: 5.27.11 [KCrashBackend]
-- Information about the crash:
* not sure what is realated to the crash, but will provide as much detail as
possible in the following steps to reproduce:
1. Perform a build of the project (either 'F8' or from the project side-bar
'build' menu button).
2. Pop the build window out of the dock and move and size it beside the
KDevelop main window.
3. click on several error or warning messages to bring up source files. I
don't know if this is related, but the crash usuall happens after several
builds. For example, turn on a much higher warning level, and navigate through
several warnings across different source files.
4. from a the source files, use the mouse hover to bring up the popup
definitions and declarations of various variables and function calls and
parameters. I don't know if this is a required step to the crash, but it does
seem associated. Meaning it doesn't seem to crash if I don't hover for info,
and does seem to crash when I do hover ahead of the consecutive `ctrl+.`
navigations.
5. mouse click to set the focus on a variable to a structure.
6. press `ctrl+.` to navigate to the definition of the
variable/structure/function; this will typically be the structure where the
variable is instantiated (e.g. a structure declared static and instantiated).
It is more consisten to start with a peripheral variable and navigate up from
the variable to the larger structure/class definitions.
7. then select another variable/structure/function/class declaration and press
`Ctrl+.`.
8. this is supposed to navigate to the definition of the
variable/structure/function/class , but will often crash instead.
9. if it does not crash, go through another `Ctrl+.` navigation from the
presented file to another variable/structure/function/class , …
In other words, it seems to crash from repeated consecutive `ctrl+.`
navigations to variable/structure/function/class definitions.
The crash can be reproduced sometimes.
