Bug ID: 520632
Summary: Crash (SIGSEGV) in Konsole::Screen::copyLineToStream
during terminal display update
Classification: Applications
Product: konsole
Version First 26.04.1
Reported In:
Platform: Arch Linux
OS: Linux
Status: REPORTED
Keywords: drkonqi
Severity: crash
Priority: NOR
Component: general
Assignee: [email protected]
Reporter: [email protected]
Target Milestone: ---
Application: konsole (26.04.1)
ApplicationNotResponding [ANR]: false
Qt Version: 6.11.1
Frameworks Version: 6.26.0
Operating System: Linux 7.0.10-arch1-1 x86_64
Windowing System: Wayland
Distribution: "Arch Linux"
DrKonqi: 6.6.5 [CoredumpBackend]
-- Information about the crash:
Description:
Konsole crashed unexpectedly with a Segmentation Fault (SIGSEGV). Right before
the crash, I was using `gemini-cli` and then opened `aichat`. During this time,
I noticed a massive spike where the CPU usage hit 100%. Based on the stack
trace, the crash occurred in `Konsole::Screen::copyLineToStream` which was
triggered by `updateImage`. It seems Konsole failed to handle the text
rendering/processing during the high CPU load caused by the AI CLI tools.
Steps to reproduce:
1. Open Konsole.
2. Run `gemini-cli`.
3. Open/run `aichat`.
4. Observe the CPU usage spiking to 100%.
5. Konsole crashes.
System Environment:
- OS: Arch Linux
- Display Server: Wayland
- Framework: Qt 6
The reporter is unsure if this crash is reproducible.
-- Backtrace:
