Description jeuamix 2024-07-18 11:49:23 UTC 
When entering extremely long operations in krunner, this will result in an exponential use of memory

SUMMARY

This operation: 2+2*999999999999999999999999999999999999999999999999999999999999999999999999
Will make baloorunner use 2.3GiB of memory




STEPS TO REPRODUCE
1. Open krunner
2. type very long operation (ex: 2+2*99999999...)
3. Notice steady increase in memory usage

OBSERVED RESULT
baloorunner fills up ram exponentially (eventually slowed my computer to a crawl)

EXPECTED RESULT
baloorunner doesn't use 32GiB of ram / limits the max size of calculation
