SUMMARY
Using KRunner to do simple calulation (EX. 10+20+30+60+92+7) result in baloorunner using GBs of RAM

STEPS TO REPRODUCE
1. Open KRunner
2. Write a simple calculation
3. Add other terms to calculation (Ex. +1+2)

OBSERVED RESULT
baloorunner increased RAM consumption not giving it back to the system.
Kernel kills baloorunner.

EXPECTED RESULT
baloorunner not increasing RAM consumption

SOFTWARE/OS VERSIONS
Linux kernel: 6.14.11-300.fc42.x86_64
KDE Plasma Version: 6.4.0
KDE Frameworks Version: 6.15.0
Qt Version: 6.9.1

I can reproduce this issue. It takes a bit; I do have to keep adding terms. But eventually the RAM consumption explodes to a gigabyte or more.

Likely fixed with https://invent.kde.org/frameworks/baloo/-/merge_requests/264
