STEPS TO REPRODUCE 1. Open krunner 2. paste the following: 9^€^€^€^€^€^€^€^€^€^€^€^€^€^€^€^€^€^€^€^€^€^€^€^€^€^€^€^€^€^€^€^€^€^€^€^€^€^€^€^€^€^€^€^€^€^€^€^€^€^€^€^€^€^€^€^€^€^€^€^€^€^€^€^€^€^€^€^€^€^€^€^€^€^€^€^€^€^€^€^€^€^€^€^€^€^€^€^€^€^€^€^€^€^€^€^€^€^€^€^€^€^€^€^€^€^€^€^€ 3. Enter an additional "€" 4. Watch as krunner keeps allocating memory until plasma crashes SOFTWARE/OS VERSIONS Kernel: 6.2.8-1-MANJARO KDE Plasma Version: 5.27.3 KDE Frameworks Version: 5.104.0 Qt Version: 5.15.8
Please report the bug to libqalculate
(In reply to Fushan Wen from comment #1) > Please report the bug to libqalculate I believe a timeout after a few seconds would go a long way here. Perhaps even setting a memory limit could work. Both of these solutions should be better than having plasmashell restart.

Forgot to mention, I have reported this bug to libqalculate.

Git commit 3f3bea079bb55ec70ce248d1238cd0e7e38e5261 by Fushan Wen. Committed on 08/04/2023 at 07:17. Pushed by fusionfuture into branch 'Plasma/5.27'. runners/calculator: set timeout to prevent allocating huge memory This is not exactly a memory leak. The extreme expression simply requires huge amounts of memory to calculate. The calculator runner is problematic since it does not specify a time limit for calculations, and does not even abort calculations after the window has been closed (a simple example of this is the expression 123456789!).
